I have a 2 and a 4 year old currently. We use these boxes for everything. We use them to talk about colors, shapes, to hide things under, to stack. The girls carry things around in them. My children have stepped on them without destroying them. They've thrown them. They've rolled them down the steps. They stay in use, and they stay in one piece. That's the best I can ask for when it comes to my kids' toys.
These are large and sturdy. I purchased these for my daughters first birthday, along with several other pieces for her to play with. I know they will be loved for many years.
I bought these for my almost 5 year old daughter, and I think she’ll love them! They’re big enough to use as rooms for peg dolls and Maileg mice :)
