All of these for one price! To judge the sizes the largest pinback button here measures 3'' wide. Almost all of these appear to be in excellent to mint condition as pictured. The largest one with a rainbow was made poorly. It is coming apart and there is no pin. The tin backing appears to have been made with the tin from a 12 ounce soda can.
