My daughter loves Kiwi Co. She has created some very cool projects and is proud of herself for whats shes created each month. The directions are easy to follow but also develop instruction following skills, which I am thankful for as a parent!

These kids are phenomenal, very educational, and I absolutely love that they come with instructions that my nine-year-old can follow on her own! Not to mention all the pieces come perfectly together for less preparation on my part!
