G Pen 3-Piece Slim Grinder

Every exceptional session starts with a better grind. The G Pen Slim 3-Piece Grinder is engineered with innovative micro-rounded teeth that gently separate flower into a consistent grind while helping preserve the cannabinoids and terpenes that make every strain unique.

Unlike traditional sharp-tooth grinders, the Slim’s rounded tooth geometry and smooth interior reduce friction and minimize buildup, keeping more of your flower where it belongs. The screenless 3-piece design also keeps trichomes mixed with your ground material instead of separating them away, while the compact profile is ideal for travel, everyday carry, and effortless session preparation.

Crafted from premium 6063 aircraft-grade anodized aluminum, the G Pen Slim delivers smooth rotation, lasting durability, and precision performance. Backed by independent testing from Orange Photonics, the innovative micro-rounded tooth design demonstrated the highest post-grind THC retention among multiple grinder styles tested.

Designed to produce a consistent grind optimized for vaporization, the G Pen Slim 3-Piece Grinder pairs perfectly with both the Stündenglass Modül Dry Material Vaporization Tank and the original Modül Dry Material Tank, delivering an even pack for smooth, flavorful, water-filtered dry herb sessions with the Modül ecosystem.

Smarter by design. Better with every turn.
