The Passive Cubelet is a basic building block. It carries power and data from its neighbors, but it basically acts like a smart brick. It doesn't move, sense, or change the data in any way. This Cubelet is pre-loaded with the newest Cubelets operating system, Cubelets OS 4.
- For ages 4 and up.
- Cubelets are lead free. Please see our FAQ for safety questions.
