During our recent forays (sp?) Chris chanced across this item. We have a couple of carousels that are small but this is getting really down there. Chips are not more than 5/8" across. Can't imaginge how these chips were used. Appear to be catalinite/bakelite/phenyl something or other! Box says, "plastic" BUT this is early plastic! No denominations on them. Box and all together! We love the finds and the chase!
