YJ JinJiao 3x3
The YJ JinJiao 3x3 is a concave 3x3 speed cube that slightly muted stickerless shades. The most prominent feature of this puzzle, however, is the concave design. Although it is not WCA legal, it turns well out of the box and is a fun, different feeling puzzle to solve!

Great cube turns very well and amazing for my collection
Best concave cube I've tried. Most are catchy crap with poor build quality.
Not a speed cube out of the box but it turns smoothly, looks amazing and feels great.
My new favorite cube.
Saw this cube on Damian's IG and it looked amazing. I knew it was a must pick up. Unboxed and it turned very smooth! Scratchy, but smooth and fast. Corner cutting was ok, nothing to write home about. So, naturally, I took it apart, magnetized with N48's, lubed core with Lubicle Black, Dignitas, DNM37 and Compound X. Easily got my sub-20 AOx5 and got a 15.26 single which is close to my PB single. I wish I would have dyed the blue and green pieces before magnetizing and lubing (horrible shades imo. You need nice lightning to really distinguish them). Overall, fantastic novelty cube and it would make a great gift for anyone!!!
(PS: I bought it for $6. Price is at $5 now! It's a must pick up!!!)
If you are buying this cube as a "speed cube", you are probably gonna be disappointed. The real reason you want this cube is to have something in you cube bag that is totally weird, but still solvable. This cube turns very well, better than any other concave cube. The color scheme is unique and very pretty, my only problem is the green and blue are a little close. The puzzle is very easy to magnetize. If you get it make sure you have magnets. This puzzle is a must for every collector.
I picked this up because it looked cool and was cheap, and out of the box it was how you'd expect - fast, catchy and sandy. I decided to set it up with lube just for kicks, I put gravitas on the core, screws and on the tracks, and dignitas on the pieces with 2-3 drops of DNM-37. No joke, after breaking it in with the angstrom lubes this became an amazing speedcube that I'm able to achieve some of my best times with. The corners don't hurt at all and actually seem to aid in fingertricking. I would absolutely recommend this cube if you have decent lube to set it up, or at least as a piece to add to your collection. This is probably the most fun and interesting to solve 3x3 in my collection.
