The Easter Bunny delivered these tumblers in the kids' Easter baskets. They have helped keep my kids full of water without cups everywhere or someone drinking out of my cup. I now just fill them as needed and they have a spot on the counter for the kids. They know which one is theirs...even my 2 year old will find his and drink only out of that one. Now I'm not being asked constantly for a cup or help getting water...I love them!
