Meffert’s Hollow 3x3x3 Cube is part of the the Hollow series. Scramble the cube and then see if you can solve back to a single colour per side. The hollow design looks great and no core movements are a unique experience. Although a smaller size this is still not as easy as you may think! The cube measures 60 x 60 x 60mm. Also includes a Crux Puzzles sticker.
