My 10 year old son loved this. I love that it is wooden and can last

there were several projects in one kit so my child was able to share it with a friend who happened to be over when it arrived. They worked together to put them together and experiemnt with them. They even went online for the template to make the dove.

I liked this crate I thought it was great. My son hangs the animals from his pump stand. He loved the animals and the way they moved.
