Guys, for years I was hoping someone would finally make a tiled (stickerless) black mini keychain size cube. A design that doesn't have that annoying hole in the corner cubie to hold the keychain attachment. One that will turn smooth, and the perfect size to fit in a pocket, a bag, a desk drawer, wherever. This one is the perfect design. I knew just from the photos, so I bought 5 of them as backups to keep at work, in the car, and so on. They keychain was designed to connect to a secure storage box. You can detach the keychain, open the box and access the cube. It turns well out of the box, but I put two drops of lube in it, and it's so smooth and quiet too. OMG! The only drawback on the cube is that it's not as suitable for speed cubing as the Gan 330, but that one is about 2mm bigger, so it was more designed for that anyway. This one is worth every penny guys, and I have no regrets about buying 5 of them. I might even buy a few as stocking stuffers for the family later this year. Thank you Gan, finally someone created the mini cube that has never been done before. Props! I'm so happy. Speedcube Shop shipped this package from CA to MA super fast too. Great service here, thank you.
