I used the pattern I had created by deconstructing an old pouch I had and used two different materials to sew these two flex frame pouches.
The rose gold cork fabric pouch measures 4.5 inches square and the pink leather pouch is approximately 4 x 4.5 inches.
Sometimes these pouches are referred to by different names; self closing pouch, pinch pouch, squeeze coin purse, snap top, spring frame, but are usually made using the same metal flex band hardware.
