1 Unit includes 64 coloured squares (and a couple spares). Also includes interlocking transparent frame that supports the squares to give that floating look. Frames are designed so that multiple panels can automatically interlock (on all four sides) making it super easy to create shimmer walls as large as you need, simply hang from a backdrop or ceiling atachment. Frame is roughly 30cm high and 30cm wide. ** Please note squares do not come attached to the frame. **
