Calvin's Puzzle

Product Description

The Electroplated Metal Alloy 4x4 is the heaviest 4x4 we have ever tried. All of the caps on the pieces are metal, but the internals are plastic which gives this puzzle decent performance even with its significant weight. 

Surprise your friends, train your hand strength, or just use it to start up a conversation. This unique puzzle is sure to make any cuber happy.

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.

Dented and not really metal alloy

The cube arrived dented on one of the center tiles, unable to turn in certain directions, and worst of all is not even really a metal alloy on the exterior! I'm sure there's metal underneath based on the weight, but on the outside it just looks like a cube with a polished paint. I'm working on trying to return it, but customer service is definitely lacking.

It looks like Alexandra responded to your email in less than 24 hours and offered a return after getting some pictures, but please feel free to let us know what we can do to improve.

The Super Heavy 4x4 Metal Cube is an impressive design, combining a bold design, immense weight, exceptional performance, and unmatched durability. It is great in both aesthetics and turning! it's like turning a normal 4x4 but super heavy. great cube and time to train my fingers!
