Stewart/Stand makes compact and sustainable accessories from recycled stainless steel fabric. The ultra-durable material, used extensively in many industries, is surprisingly lightweight and smooth to the touch. This vegan bi-fold wallet is a fave. Finished with classic houndstooth, which contrasts nicely with the modern steel fabric, it has an innovative interior design featuring crossing card slots. The Stewart/Stand site says that the recycled steel fabric blocks unauthorized transmission from RFID enabled credit cards and IDs. We don't know what that means but it sounds like a good thing.
