This group of 4-2 holed forest green, light green hard plastic buttons are on their original card and about 22mm wide or 7/8" and 1/8" or 3mm thick. They are sSmallly indented in the middle and shimmery like fibre optics and very smooth. The company name is H.A. Kid Co. Ltd, Toronto. My inlaws had a general store until 1965 so I know these are at least 55 years old. Please visit my booth for more new and used items to see. I will happily combine purchases paid together within a 7 day period. Thanks 5% sales tax is required within Canada.
