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.

Cool concept, poorly built

Never heard of this mod so I was stoked to try it out. Fell apart within 5 minutes of solving, exposing some poorly glued pieces that were a nightmare to reconfigure. Attempted to reglue them to no avail given the lack of info on this particular version of the mod. Gonna have to trash it unfortunately. Really disappointing for a $28 Calvin puzzle :(
