What Clients Say About GMI

“The custom grinders exceeded our expectations. The 3D engraving gives a premium feel that matches the quality of our flower — and we have been reordering for over eight years now.”

— Jacana, Jamaican cannabis brand

“We tested multiple suppliers before settling on GMI. The no-minimum order let us trial one unit first, and the quality was so consistent that GMI is now our sole grinder supplier across all locations.”

— Native Roots, Dispensary chain

“The rose gold 3D engraving turned out even better than the mockup. Customers notice the difference between this and a printed decal immediately — and the finish has held up for over a year of daily carry.”

— High Focus, Cannabis brand

“We ordered nine different custom grinders for a wedding party — each groomsman got a different engraving. GMI was the only supplier who could do that with no minimum order. The free proof came through in one day.”

— Penrose, Music label

“Working with GMI was straightforward — they sent a digital proof before machining, and the finished grinders matched it exactly. The 3D engraving depth and finish quality are on another level compared to the printed grinders we used before.”

— Run The Jewels, Music brand

“I needed custom plastic grinders for a merch run and GMI delivered fast. The acrylic ones are light, the print quality is sharp, and the price per unit made sense for a giveaway item.”

— Ari Shaffir, Comedian and podcaster
