Step 1: Get Parts/Tools
1.Old Floss Box
(I'm sure you have 7 of these that are unopened, and we all know why.)
3.The item you will put in the box
(In my case the splitter)
1. Single Hole Punch
(I used a paper hole punch, but I'm sure it would have been much easier with a leather punch)
Step 2: Get Punching
You will make one hole punch on the front, top, left side.
The next punch will be on the the left side near the top. Make sure the keychain ring will be able to go through these two holes.
