Mini Portrait Phone Stand for Wallet Cases

I use my phone for reading books (with Moon+ Reader and Kindle) and I prefer portrait mode for this.  I wanted a simple stand that's always available without having to carry extra stuff around with me.

This print fits into the wallet case for my phone and will support the phone in a portrait format.  For landscape format I just use the phone case to support it.
