Frequently Asked Questions

How fast does the The Keeper™ By Hemper ship?

Orders placed before 2 PM ET on business days are processed the same day. Every The Keeper™ By Hemper order ships tracked, in plain discreet packaging, typically arriving within 2–5 days.

Why do grinder pieces matter (2 vs 3 vs 4-piece)?

A 2-piece just grinds. A 3-piece adds a storage chamber below the teeth. A 4-piece adds a fine mesh screen that sifts kief into a bottom chamber — the bonus layer that accumulates into a potent reward over weeks of normal use.

What is the kief catcher actually catching?

The screen sifts off trichomes — the resinous crystals that carry most of the potency. Collected kief can be sprinkled on a bowl, pressed, or saved for special occasions. A coin left in the kief chamber helps knock more through the screen.

How do I clean a metal grinder?

Disassemble and freeze it for 30 minutes (resin snaps off cold), brush out the loose material, then soak parts in isopropyl alcohol and scrub with a brush. Rinse, dry fully, and it grinds like day one. Save the iso — evaporate it to recover the resin if you like.

Aluminum vs zinc grinders — is there a difference?

Aircraft-grade aluminum is lighter, machines sharper teeth, and lasts for years of daily use. Zinc alloy is heavier and cheaper — fine for occasional use. If a grinder is suspiciously cheap and doesn't say aluminum, it's zinc.

Why does my grinder get hard to turn?

Resin builds up on the thread ring and teeth. A quick brush-out weekly and an iso deep-clean monthly keeps it turning smoothly. Storing it in a warm spot (not the fridge) between cleans also helps the threads move freely.
