Why choose this grinder?

🌿 Even grind in just a few twists

Spiral-cut teeth machined from a solid block slice your herbs cleanly without crushing them. Essential oils, aromas, and the airy texture ideal for cooking, infusions, or vaporizing all stay intact.

💎 Pollen chamber with fine mesh

The 4th compartment captures pollen and kief through a fine stainless steel mesh. A scraper is included so every grain is collected — nothing wasted, everything put to use.

🛡️ Anodized aluminum, magnetic lid

Aviation-grade anodized aluminum body: lightweight, corrosion-resistant, and tough. The magnetic closure keeps the parts perfectly aligned at every use, without sticking.

Frequently asked questions

Is the 40 mm grinder right for all herbs?

Yes, this diameter is ideal for aromatic herbs (basil, thyme, rosemary, mint, sage), spices, and dried plants from your indoor garden. For larger volumes, go for the 50 mm model.

How do I keep my grinder in top shape?

Disassemble the four parts after each use and brush the teeth with a soft brush. A blast of compressed air or an isopropyl alcohol clean every 15-20 uses keeps the mechanism running smoothly.

Pro tip : pair this 40 mm grinder with an airtight storage pouch to preserve your ground herbs and keep their freshness longer.
