These building blocks for kids turn simple joint sticks into robots, animals, vehicles and anything else a young builder can imagine. Each skeleton building block connects at flexible joints, so kids can pose, rebuild and invent new models again and again. Choose from a small 18-piece starter bag up to a 301-piece set in a storage box for big group builds.

FAQ
What are skeleton building blocks?
They are joint stick pieces that connect into posable frames. Kids can build robots, animals, people, vehicles and their own creations, then take them apart and start again.
Who are these building blocks for?
They are a kids toy for curious young builders and family build time. Adult supervision is recommended for young children.
How do kids play with building blocks like these?
Start by joining a few sticks into a simple frame, then add limbs and joints to pose it. The 18-piece bag is a low-cost way to try them, mid-size sets of 55 to 102 pieces suit one child, and 147 pieces and up give enough parts for larger models or several builders.
Adult supervision recommended for young children.
