This is so small, perfect for small hands.
I bought two and have made them into earrings. :)
I may get a third to make a necklace pendant.
I will also add that I did have to lube this cube because it was sandy OOTB. I can understand that if you try to speed solve this without adding lube, it could snag and pop with any brute force. That said, this cube is a novelty item and most likely never intended for regular use or to be a main.
This is impressive that as small as this is that it's 100% better than I'd experienced with other tiny 3x3 cubes.
Ps...the colors are very feminine perfect if you like pink and soft pastels. This is not the classic Rubik's B.O.Y. colors. (That's Blue Orange Yellow clockwise UFL for the new cubers)

It's definitely the best sized 3x3 keychain out there. If all were this size they'd all be great. That said, it turns like... I won't swear on here, but I'll say "doody". It turns like doody. It's fine if you just want a fun little thing to do. Like I said, it's hands down the best sized keychain 3x3 out there though. The colors are super pastel, if you care about that. As far as the other reviews saying it's super fragile, haven't seen it yet. I've had it in my pocket for what, a couple months now, still hasn't fallen apart like everyone says it does within days. Maybe I just got the good one. I'll give it 4 stars for it's budget.

YJ Mini Pillowed 3x3 Keychain Cube (2.0cm)

I bought this cube because I figured if I had a bunch of small cubes why not have them all. This cube has a "prong" core like the maru nano 15mm cube but turns just as good as the 30mm cubing classroom 3x3. It is tight enough that you won't have stability issues but loose enough to turn well. This cube doesn't corner twist like the cubing classroom 30mm and isn't scratchy like the maru 15mm.
Overall great nano cube, but a stickerless bright variant might be nice.

So small it is small enough to actually turn it to a force cube (dodo cube) with 8 of these

This is the perfect size to actually carry in your pocket as a keychain. It also turns well enough to do a solve, and looks neat. However, it's not durable enough to stand up to everyday wear in my pocket. My first one exploded while I was locking the door, showering pieces all over my front yard. No problem, I got a second one since they are so cheap. After a few days, I put my hand in my pocket and felt a bunch of pieces instead of a cube. It probably exploded when I went through a turnstile. So, it's a fully functional and fun little puzzle, but it can't survive everyday wear unfortunately.

Great addition to my keys! Love how it turns

this cube is cool looking but it pops a lot. There is absolutely NO corner cutting at all, and instead of doing U' I end up having to do a U3. This cube when it pops the corners will fall apart into 3 pieces and they're so hard to find and put back together.

The colors are adorable, the key chain is really pretty, high quality, and easy to attatch and remove with a small lobster clasp. Turns better than the Maru Nano, but it slightly catches occasionally.
