Kokuyo One-Patch Stamp

Kokuyo's One-Patch Stamp is a nifty little device to reinforce your hole punched documents.

Kokuyo's unique roll-out mechanism lets you stick the hole reinforcers as easily as using a stamp. Plus, there's no backing paper, so no unnecessary trash!

The hole reinforcers are clear, so you can still read what's underneath after reinforcing your papers.

There is a guide in the center of the lid to help line up with the punch holes. 

It's a refillable design that's both simple and quick to use. Just pull out the core and pop a refill in. (Refill stickers are sold separately)
