Mesh screens provide the perfect pollen sift, leaving out unwanted plant matter.

Frequently Asked Questions

How fast does the BIGFUN! Large Grinders ship?
Orders placed before 2 PM ET on business days are processed the same day. Every BIGFUN! Large Grinders 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.

How to get it right

1

Load the edges

Place material between the teeth, not dead center - the center pin does not grind. A few firm twists and you are done.

2

Work the kief screen

A coin in the middle chamber knocks extra kief through the screen. Check the bottom chamber monthly - that is the bonus stash.

3

Keep it turning

Brush out after use; freeze then iso-scrub monthly. Clean threads keep it smooth for years.
