The picture below shows a larger view of all (10) Old Gum Ball Machine Prize Ring Toss Puzzle Toy Charms in this lot. These are not dated but they are from the 1960s. On the bottom they are each marked “HONG KONG”. The jugs are made of clear hard plastic. Inside there is a colored plastic post and several color rings to try to get on the post. All ten of these for one price! The jugs each measure 7/8'' tall. They are all in mint condition as pictured.
