We have 10 Upholstery Vinyl Pins in an olive green from the 1960's. They measure about 1 5/8" across. The tacks on the back measure about 3/4" in depth - these were made for chair tacks on the chair itself. They are in good condition, there are a few extremely light spots, almost not visible - I couldn't get them to come out in my photo's. These may come out with a good cleaning - I quickly cleaned them with a damp cloth only.
