Our Promise to You

All of our products are guaranteed to be free of defects, or we will replace and reship at no cost to you. Please contact us within 4 weeks (28 days) past the delivery date to report any issues with items you have purchased.

Please note that some new cubes when being used for the first few times may experience what is termed a "pop". This is when one or more parts of a puzzle pop out without any damage actually being done to any of the pieces. This also occurs from time to time during normal usage. Pops are typically not considered a defect if the parts which come off can be reassembled by hand.

The corners on 2x2 puzzles should not be twisted as doing so may snap the piece. Damage caused by corner twisting is not considered to be a defect.

Fun puzzle

Very fun puzzle, and it's a bit more challenging than it looks. I highly reccomend it. It had multiple deep scratches on the surface and a ton of spring noise, which caused me to take a star off, but otherwise it was very well made and fun to solve.

Very good!

This turns very smoothly and well! Quite a bit more challenging than a regular mirror cube, but that just made it more fun. I have no complaints with it.

Quite the challenge

I like the way this cube turns. It's fun to scramble & it's a challenge to unscramble. Very nice experience.

A Better Mirror Cube than the Mirror Cube

I'm fairly new to cubes outside the standard 2x2 to 7x7, and this was my first order from the Cubicle, I got both this cube and a Mei Long Mirror Cube for some shapeshifting action, and I have to say this cube has been so much more fun and just feels better put together. The other cube feels like it's going to pop in my hands at any point and can corner twist pretty easy, but this cube feels and operates solidly. Plus, I just personally think it looks better

Got the Black and White

This one turns fairly smoothly and it’s only slightly more difficult than the mirror cube. Overall, I really like the concept and it’s strange enough looking to be a good conversation piece.
