How can I make extra rubber bands for my folding coin?
Need some inside info about the making of them...

If it's similar to the one I have the best source would be a local orthodonist office... I believe they are the same type used on braces for teeth.

Penguin Magic also sells refills here.

Yeppers that would be correct. My daughter kept asking where her rubberbands for her braces were going.
She finally realized I was using them for my folding coin!

Haha......I cut mine from my old slingshot's rubber tube. much stronger...much better than the original.

The refills that magic shops usually sell are pretty bad and they break in few minutes while using. I have got mine from local dentist as well and I haven´t had to replace my band in 6 months.
There has also been advertisements on Euro folding coins that don´t use the rubber band. I haven´t got any yet though...

I got my bands for the folding quarter 12 for a dollar at the local shop. before that I tried my orthodontic rubberbands that I had when I had braces but they were too big... maybe I should get the half dollar size so I can use the rubberbands that I got from ortho
