If you want to carry it, and not in a pocket, then I can make a pouch for it. Doesn't much matter what it is. Magazine pouches, multitool pouches, knife pouches... I'm your Huckleberry.
Belt wallets are pouches with flaps designed to hold credit/debit cards and cash. They can be made in any thickness. They normally come with a spring steel clip on the back but can be made with a belt loop as well. It keeps you from sitting on your wallet and throwing your back out. They can also be lined with an RFID blocker since all the cards seem to be "chipped" now. With the belt clip, a spare car or house key and be put between the clip and the pouch, so you always have a spare key with you. This is the type of wallet I personally use. Like everything I make, it has a lifetime warranty.
Cell Phone Cases
I will need the exact dimensions of your phone with whatever protective case you have on it. I will then make the case a little loose so you can get your phone out of it. Vertical or horizontal carry, it doesn't matter matter. Your case will be built from scratch. My case will outlast your phone.
