Key Takeaways
- GMI is the only one of the three with no minimum order. Buy one grinder or a thousand. MunchMakers standard tier starts around 25 units (as low as 6 on promo styles), and SmokePromos starts at 50 units (30 on some lines).
- GMI offers real 3D metal engraving. The logo is raised and embossed out of the metal, finished in gold, silver, black, or rose gold. Neither MunchMakers nor SmokePromos offers this finish on their grinders; both use etching or surface print.
- Entry cost favors the no-minimum supplier. GMI starts at $50 for a single grinder. Placing a standard first order with MunchMakers runs about $450, and with SmokePromos about $475.
- Compare the whole cost, not just the per-unit price. Setup fees, minimums, and what is included free (scraper, box, proof) change the real total. GMI's pricing is fully public on the shop page.

Summary
Choosing a custom grinder supplier comes down to a short list of decisions. What is the smallest order you can place? What does a first order really cost? Can you see your logo before you pay? Does the branding last? This guide compares the three suppliers a dispensary, brand, or merch buyer is most likely to reach: GMI Custom Grinders, MunchMakers, and SmokePromos.
All figures come from each supplier's publicly listed custom-grinder programs at the time of writing. Nothing below is a guess. Where a supplier offers more than one tier, that is noted, because the lowest available tier changes the value story.

What You Are Really Comparing
Minimum order is the smallest quantity a supplier will produce and decorate in one run. It sets how much cash you need to commit before you have held the product.
Entry cost is the total you pay to place a first order at the minimum. It is the minimum quantity times the per-unit price, plus any setup fee.
Branding method decides how long your logo lasts. A true 3D metal engraving leaves the logo raised and embossed out of the metal. A printed or etched logo sits on the surface and wears with daily use.
Proof process is whether you can see your design before you pay. Some suppliers email a mockup. Some offer an instant in-browser preview.
What is included free changes the real cost. A scraper, a box, and a design proof are sometimes billed as add-ons.
These five factors matter more than a headline per-unit price, because the headline number never reflects setup, minimums, or add-ons. This comparison is built around them.

Minimum Order
| Supplier | Minimum order |
|----------|---------------|
| GMI | None, 1 unit |
| MunchMakers | ~25 standard; as low as 6 on some promo styles |
| SmokePromos | 50 standard; 30 on some lines |
GMI machines and decorates a custom grinder in any quantity. There is no floor, so a brand can test a single unit before committing to a run.
MunchMakers states that most of its grinders start at around 25 units, with some promotional styles going lower (MunchMakers custom grinders, retrieved 2026). Its homepage notes the floor can be as low as six units on select styles.
SmokePromos lists a 50-unit minimum on its standard four-piece grinder, and a 30-unit minimum on some newer branded lines (SmokePromos four-piece grinders, retrieved 2026).
For a first test order, the no-minimum supplier removes the risk of holding stock you have not validated. The practical difference between 1 unit and 30 to 50 units is the difference between a $50 test and a several-hundred-dollar commitment.

Entry Cost
| Supplier | First order | Notes |
|----------|-------------|-------|
| GMI | From $50 | Single 2-part grinder; no setup fee for standard finish |
| MunchMakers | ~$450 | About 25 units at standard tier |
| SmokePromos | ~$475 | About 50 units; plus a $40 art setup fee for new designs |
GMI's pricing is public and self-serve. A single 2-part grinder starts at $50, configurable in the in-browser customizer.
MunchMakers does not publish a universal per-unit price across all styles. At its standard 25-unit tier, a first order lands near $450.
SmokePromos publishes tiered prices. Its four-piece grinder is $9.50 per unit at 50 to 199 units (SmokePromos four-piece grinders, retrieved 2026), so a 50-unit first order is $475, before the $40 one-time art setup fee for each new design.
The entry cost is where no-minimum wins hard. If you are testing a design, a single $50 grinder beats a $475 initial outlay. For a serious bulk buyer, the per-unit price gap narrows as quantity rises, and GMI's pricing drops too with volume.

Branding Method: 3D Metal Engraving vs Print
3D metal engraving is a separate CNC process. The logo is embossed out of the metal so it stands raised off the surface, then finished in a metallic tone. It does not fade, peel, or wear off, because the mark is part of the metal itself.
GMI offers 3D metal engraving finished in gold, silver, black, or rose gold. This is the highest-durability and highest-perception option in the category.
Neither MunchMakers nor SmokePromos lists a true 3D metal engraving finish on its grinders. MunchMakers offers surface decoration such as UV print and anodize. SmokePromos offers decorated grinders built around etching and print.
The tradeoff matters for repeat impressions. A logo engraved into metal stays sharp as long as the product lasts. A surface print can fade with daily use. For a branded item your customer uses and shows, the engraving carries the brand further.
---
Proof Process
GMI gives an instant in-browser customizer where you upload a logo, preview it on the lid, choose a finish, and see the design before payment.
MunchMakers emails a free digital mockup before production, which is a solid proof step (MunchMakers, retrieved 2026).
SmokePromos uses an emailed proof as part of its art approval flow.
An instant self-serve preview shortens the decision. The other two still prove the design, just through an email exchange rather than a live preview.

What Is Included Free
| Item | GMI | MunchMakers | SmokePromos |
|------|-----|-------------|-------------|
| Custom scraper | Yes, designed to match | Not standard | Plain scraper |
| Box | Free on 100+ units | Add-on | Add-on |
| Design proof | In-browser, instant | Free digital mockup | Emailed proof |
A matching scraper is a real part of the perceived value. GMI includes a custom scraper designed to match the grinder. SmokePromos includes a free scraper but a plain one. MunchMakers does not include one as standard.
A branded box matters at retail. GMI includes a box free on orders of 100 units or more. The other two treat custom packaging as an add-on.

Which Should You Choose?
Pick GMI when you want to test a design with no lock-in, buy at any quantity, or get a 3D metal engraving that lasts. The no-minimum and fully public pricing make it the low-risk starting point for a brand or dispensary validating a new item.
Pick MunchMakers when you value a wide material and product range and are comfortable with a roughly 25-unit starting tier.
Pick SmokePromos when you want a well-known name with fast standard turnaround and are planning a run at or above its 30 to 50 unit minimum.
For most first-time buyers, the deciding factor is the size of the first commitment. If you are not yet sure your customers want a branded grinder at all, a no-minimum single order lets you find out without betting a few hundred dollars.

FAQ
Which custom grinder supplier has the lowest minimum order?
GMI has no minimum order, so a single unit is enough. MunchMakers starts around 25 units standard, with some promo styles as low as 6. SmokePromos starts at 50 units standard, with 30 on some lines.
Do MunchMakers or SmokePromos offer 3D metal engraving?
Neither lists a true 3D metal engraving finish on its grinders. Both use surface decoration such as etching or print. GMI offers 3D metal engraving with the logo raised and finished in gold, silver, black, or rose gold.
What is the cheapest way to start with a custom grinder?
A single no-minimum order is the cheapest entry: GMI starts at $50 for one grinder. A standard first order with MunchMakers costs about $450, and with SmokePromos about $475 plus a $40 setup fee.
Do you have to commit to a large quantity to get a good price?
No. GMI prices drop with volume with no minimum to start, so a small test order gets real per-unit pricing. Its shop shows the tiered price at every quantity.
Is the scrapers and box included, or an add-on?
The answer varies by supplier. GMI includes a matching custom scraper and a free box on orders of 100 units or more. SmokePromos includes a plain scraper. MunchMakers treats the scraper and box as add-ons.

Conclusion
The three suppliers solve the same job differently. GMI removes the minimum and the setup risk, publishes its pricing, and offers a 3D metal engraving that outlasts surface print. MunchMakers and SmokePromos offer broader ranges and recognizable names but start at higher minimums and use surface decoration.
For a brand or dispensary deciding where to start, the honest tiebreaker is the size of the first bet. A no-minimum single unit is the cheapest way to validate a design, and the cheapest way to see whether your customers care. Once you know the design works, volume pricing is available either way.
Start small. Try a single custom grinder with your logo. If it moves your customers, scale it up.
