This one-of-a-kind cube comes with a little cube pouch, set of stickers, and also the cardboard cutouts to make your own nano cube box and nano cube stand (tape or glue required). It also comes with a set of tweezers to help with assembly, and to help pick up the cube.

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.

I don't think I'll put it together, but it's still beautiful. The cube is adorably small, and absolutely key to any collection.

Fun but be careful

this cube was so much fun to put together and is a great novelty cube for any collection. I have found when It locks up pieces can pop off the cube and they are very hard to find. So be careful when solving, don't try solving it while standing over a basket of me, it will take you forever to find the pieces.

I really like this one! If you take your time and work with each piece to make sure all burr's are removed you will have yourself a very nice usable puzzle. I do hope the cubicle will have 'smaller ones available in the future!

Simple and teeny

The cube is adorably small, and absolutely key to any collection.

Works about as well as youd imagine a 1.9cm cube with Lego-like snap-in middle pieces. The lube they provide will serve no purpose being in this cube, so use it in another cube you have; its good stuff. Good novelty item, fun to build, and worth the money for the reactions I get when I show people

Great puzzle... for its size

The puzzle was easy to assemble and looks great in a collection. The sticker shades look really good. The puzzle is very small, and you can take it anywhere. The layers are not stiff, but not fast either. I really love this puzzle.

Matias V.
Surprisingly good!

It turns surprisingly good, it's in fact smoother than my 2.5 cm cubes.
The kit contains 2 cores, which is great because one of them seems a little bit looser which makes the pieces pop out when twisting the layers.
Perfect size, if it was any smaller it wouldn't be very practical.

fun and a good thing to show off

it pops even if you barely turn it in one way and has way to small of parts but comes with free lube and a pair of tweasers which dont do anything to help you build it apart from put the stickers on but it is great to show off

Review Title (Optional):

Doesn't pop for me in fact I give this cube to non-cubers all the time they don't usually pop it either it doesn't corner cut very much a little less than a regular cube by Rubik's it turns very fast for what it is. It catches a bit after a month never after 9 months but when you first get it it catches a crap ton i just put 1 or 2 drops of Maru in it. It's a very big attraction at school which can be annoying at times but it can also be in a good way so yeah its a pretty good cube.
