The file on your finger.
Bite Buster is a spinner ring with a real nail file built into it. Spin when you fidget. File when you would have bitten. Invented by a nail biter who got tired of never having a file when it counted.
Starter $29 · Signature $72 · Made in Denver
Signature study — window open on the grit.
01
It's on your hand
A file in a drawer does nothing. This one is already on the finger that was going to your mouth.
02
It spins
The outer band is a fidget. Idle hands get a rotation instead of a hangnail.
03
The grit is a refill
Starter is a wrap you replace. Signature is a cartridge you snap. The ring stays.
Signature
Inner band holds the grit. Outer band is the window that spins.
Drag to spin the outer band
Insert
The inner band stays on your finger. The outer band is the one that spins. Pause the window on a fresh patch of grit when the old one goes smooth — or hide it toward your palm when you want a plain band.
From the inventor
I bit my nails. I printed a ring. I actually wore it.
I'm Dustin. Denver. The cheap ones — 3D printed, grit paper glued on — are not only nice to wear, they work. The nicer ones will let you swap the grit like a cartridge when it is worn out, and keep the outer ring for good. This site is the shop, the waitlist, and the desk I am using to finish the provisional patent.
