Received LV iPhone wallet as a gift, and when I upgrade to iPhone X some years later the design had changed. Rather than buy a new wallet, I researched the one element which kept me from making my own, the non-sticky substance that the phone attached to.
After much research, there are two products on the market, the below listed one is what I believe LV uses to stick the wallet and phone together without the use of additional hardware.
They can make custom orders/runs etc. I bought the sample pack and that was enough for me. A word of caution, one company made a wallet where the suction came in contact with iPhone screens and it ruined/left a mark on that small section. So, don't adhere it to phone surface.

I can't say I've seen this before! A very interesting material.
I wonder if there are any other applications for it in leathercraft regarding products or even tool storage.
