Vintage Box with Purple Velvet

I am not certain what this box was originally used for or what instrument came in it. The felt/velvet is fading in color. There is a button behind the material that when pushed opens up the box. The material on the outside of the box is starting to split on the corners and wear away. The box measures about 7 inches in length by about 4.25 inches wide. The compartment when closed has about 3 inches of depth of storage space. Please see my store for many more great items.
