These are made from the same type of plastic as the milk rings all the gliders seem to like, except mine! My husband's boys like milk rings but my girls have always ignored them. I found these "bracelets" and gave them to my girls and they couldn't wait to "wear" them and carry them around. you will get 12 rings, 3 of each color.

If you have very "fluffy" gliders, you may want to cut the rings. They will still hold their shape. I cut one in the photo to show you.
