The QJ Super Square One 4SQ1 cube, also called 4SQ1 and SQ1, is a fun and very interesting new cube by QJ. The sides are like a 3x4 layer cube but with two different size panels. The top and bottom has a circular center surrounded by 3 layers of angled shapes. Definitely a new challenge! Size 6cm x 6cm x 6cm ABS material PVC stickers Black plastic color
