The DaYan + MF8 4x4 V1 is the first 4x4 made by DaYan and MF8. It measures 66mm across and its edges feature "wings" to help keep them them from popping.
Note: The cube comes in a green box, but it is not to be confused with the newer DaYan + MF8 4x4 V2 (also 66mm) that has a different internal design.
