This is a card case made from the edge of a tatami mat. It has two card slots (see photo). This is a handmade item I received from a tatami shop near my parents' house. I don't use it, so I'd like to give it to someone who wants it. Width: 7.5 cm Height: 10 cm Please understand that there may be some slight errors as I, an amateur, measured it roughly. I am an amateur when it comes to inspection, so there may be oversights. Also, please purchase with the understanding that this item has been stored at home for a long time and is a used item.
