This original carded set of 6 shimmery or pearly looking silver gray buttons are very smooth and have a watery or fibre optic look. They are made of hard plastic and have shanks on the back. I am guessing these are out of the 70's or 80's sometime by the price and look of them. They are on their original cards and about 10mm wide or just shy of 1/2" and about 1/4" or 2mm thick. Brand name is Stylrite and are held on with tiny pieces of wire. I will happily combine purchases paid together within a 7 day period. 5% GST Sales tax is required within Canada.
