100% new and high quality. This is a new type of building block, without complex parts or protruding connectors, which can be easily assembled and disassembled. We have combined the characteristics of my world and LE-GO building blocks, cleverly using powerful magnets that allow any side of the building block to be connected. At the same time, we use the ideal shape of a cube, just like pixels on a computer, to create various exquisite shapes through different colors.
