Custom-made for specific phones (for iPhone 12 and 15 Pro Max from very happy customers shown), or for generic sizes.  Let me know which phone you have, or general dimensions desired, and I will make a custom wet-mold (if a new size) and will permanently form the cell phone pocket.  Need a different style, colour, hole position (maybe a strap or some other attachment method?) just let me know.

These are hand-stitched and will last a very long time.
