Query: Fun, colorful, love the holes and numbers in the underside/bottom

My son loves these. They are fun. He loves them in the bathtub, too. There are little holes in the bottom that work as a strainer. The number of holes correspond to the number on the bottom of the cup. Pretty cool bonus. It's the simple things that make it nicer. I just wish they stacked a little easier.
