All toys are designed and handmade by me! This means they are all slightly different (makes em unique and I never seem to get the same results anyway). Feel free to buy them for children, but their handmade nature makes them not so durable. I've had my lovely nephews destroy pieces in minutes. I don't have the industrial know-how to make them kid proof. They are not suitable for the very young, there are buttons and other bits that cause little guys to choke. I wouldn't chance it
