As you see this is a pouch made from 2 pieces of leather sewed together. as you see this was made by Stemco Instruments and was to be used with a chart analyzer. You can use it to protect DVDS pr CDs. You can take it apart and make small leather items of your own, such as crafts. I forgt to measure but it is about 7 inches across. 5 pouches is 1 unit.
