Bicycle Inner Tube Phone Wallet Holder

This holder works for phones with or without case. I use this holder for my minimalist wallet. You can also use this holder for credit cards and keys.

1. Bicycle inner tube (of 2.2" MTB tire)
2. Scissors

1. Cut approximately 0.5 mm of the inner tube. You'll need two of these.

1. Loop one of the inner tube crosswise from the corners; upper left corner to lower right. First croswise loop will serve as a base grip which will prevent slippage. It is especially useful for the phones/cases with slick surface.
2. Do the similar for the other corners. That's it.

Notes

Loops do not affect the functionality of the buttons (with or without case).
