Ongrok Mini 4 Piece EZ Grinder – 2.2″

The quarter-turn locking system is a mechanism that secures the main herb storage compartment of the Ongrok Mini EZ Grinder with a deliberate 90-degree rotation rather than multi-rotation threading. To open the compartment, rotate it a quarter turn in one direction until it unlocks. To close, rotate back until it clicks into the locked position. This design prevents the compartment from opening accidentally during use or transport, and it eliminates the threading failure mode — where resin buildup in standard threads causes the compartment to seize and become difficult to open — because no threads are involved in the locking mechanism.

The kief screen in the Ongrok Mini EZ Grinder is designed to be removed for separate cleaning rather than requiring the user to clean it in place. To remove it, lift the screen by its handle and rotate it counter-clockwise until it releases from its seat. With the screen detached, both the screen itself and the chamber below it can be cleaned thoroughly. Reinstall the screen by placing it back in position and rotating clockwise until it seats. This removable design makes cleaning the most difficult part of a 4-piece grinder — the mesh screen — significantly more accessible than screens that are fixed in place.

The Mini and Premium EZ Grinders share the same core features: aircraft-grade aluminum construction, 33 triangular teeth, quarter-turn locking system, removable kief screen, and neodymium magnetic lid. The difference is size. The Mini is 55mm (2.2 inches) in diameter, while the Premium is 63mm (2.5 inches). The Mini is the more compact and portable option for personal daily carry, while the Premium provides a larger grinding surface, more storage capacity, and enough room in the catch chamber for a small humidity pack for extended herb freshness. Both are 4-piece designs with kief catchers.

Yes. The catch chamber section of the Ongrok Mini EZ Grinder can be used as a portable herb storage compartment when the grinder is sealed with the quarter-turn lock. The neodymium magnetic lid further secures the top, keeping herb contained and reducing odor during transport. The catch chamber at the 55mm size is appropriately sized for personal daily carry quantities of ground herb. Users who want to store herb for extended periods can consider adding a small boveda or humidity control packet to the catch chamber to help maintain freshness.

The 33 triangular-shaped teeth in the Ongrok Mini EZ Grinder produce a medium-to-fine grind output. This consistency suits most everyday herb consumption methods including packing hand pipes, loading bowl pieces, loading water pipes and bongs, rolling joints, and loading most dry herb vaporizer chambers. The triangular tooth profile cuts through herb efficiently with each rotation without producing an over-pulverized powdery output. For users who want a coarser output, fewer rotations of the lid produce a less refined grind.

Remove the kief screen by lifting its handle and turning it counter-clockwise. Harvest accumulated kief from the catch chamber with a small brush or scraper before cleaning to preserve the collected material. Separate all four pieces. Soak the aluminum components and the removed kief screen in isopropyl alcohol for 20 to 30 minutes to dissolve resin from the triangular teeth and chamber walls. Brush away dissolved residue, rinse with warm water, and dry completely before reassembling. Reinstall the kief screen by placing it in position and rotating clockwise until seated.
