The Stellar Ultra Mirror 3x3 is a mirror cube in solid blue from Stellar Cube's premium Ultra line. Every face is the same colour, and the pieces are cut to different sizes instead, so the puzzle is solved by shape rather than colour: when you scramble it, it twists into an uneven, shape-shifting block.

If you already solve a 3x3, the mirror cube is a new challenge, because you have to read the pieces by size and depth instead of colour. It also makes an eye-catching display piece on a desk or shelf, and comes in the brand's rigid Ultra gift box, which makes it an easy gift for a cuber.

Features:

• 3x3 mirror cube, solved by shape instead of colour
• Solid blue finish
• A fresh challenge for anyone who can solve a 3x3
• Ships in Stellar's rigid Ultra gift box
