Set of 5 Vintage Plastic Fibre Optic Round and similar items

This is a set of 5 vintage plastic buttons by le chic. These plastic buttons are round with raised center and a rim. They have 2 holes and have a fibre optic shimmery look. I had a very hard time trying to get a good picture because of the shimmery look to them. I would say they are a copper brown color. They are 20mm or 3/4" wide and 1/8" or 2mm deep. They are flat 2 hole type and held together with a piece of wire at the back. My inlaws had a general store until 1965 so I know these are at least 55 years old. I will happily combine purchases paid together within a 7 day period. Thanks 5% GST Sales tax is required within Canada.
