We purchased these for our 6 month old baby to make a travelling ring set as she loves to chew on rings. These are by the one of the best purchases we have made for our baby. She loves them! We attached them to her car seat for travel and it keeps her entertained for a great part of the trip. They are really great for shopping as well. We can attach toys to them and to the basket and if she drops them they don't fall on the floor. I would highly reccommend these for any one with an infant! I just wish we would have bought them sooner!
