This is a handmade card pocket and key case that can hold larger keys. It's made of simple black-dyed vegetable-tanned leather. If you put your driver's license in it, it can be kept with your car key, so you can avoid forgetting things at work, even if you separate your wallet. The last image is of a key case of the same pattern, but in reverse. Please limit the number of cards to 3-4. (What is vegetable-tanned leather? It is genuine leather, originally a natural skin color, that is commonly used for everyday items, etc., tanned with tannins. It brings out the natural beauty of the leather and allows for carving and dyeing, offering a wide variety of options.)
