This lot of plastic buttons features a unique assortment of shape and tiger eye design. With a quantity of 13 buttons, this vintage (or vintage-looking) collection is perfect for collectors or crafters. I believe these are plastic. These buttons would be a great addition to any sewing or crafting project, and their unique designs are sure to make any item stand out. Please check the pictures and email me with questions. I recycle packaging for shipping when possible. Thank you for looking.
