It worked. ### ⭐⭐⭐⭐⭐ Coolest cubes ever! *by C***R on July 20, 2023* Got these as a fidget for my son so he'd having something to do after conquering the classic rubik's cube. They're high quality and move smoothly. They have a nice weight to them, so they don't feel cheap. They're challenging but not impossible. I like the metallic rectangle one the best. ### ⭐⭐⭐⭐ These were a lot of fun to figure out *by H***N on October 4, 2016* For the price you can't beat this. These are 4 shape mods to the regular 3x3 cube, meaning you solve them similar to how you solve a regular 3x3. These were a lot of fun to figure out, especially the axis cube or angle fluctuation cube how it is listed here, that one I found to be the most challenging. My only issue is that on two of the cubes a few of the center pieces face plates tended to fall off very easy, I had to put a small dab of superglue to keep them from falling off with every turn. Other than that minor issue these cubes turn well and are fun to solve. I would recommend them to anyone looking for a challenge after completing a 3x3. ## Frequently Bought Together - YJ Cube Set - 4-Pack, Includes 3x3 Fluctuation Angle & Mirror Puzzles, 2x3 Wheel & Square King Cubes - Cube Twist 3x3 Stickerelss Speed Cube Vivid Color Magic Puzzle Toys Puzzle Boxes(Twist 3rd Order) - Gear Cube 3x3 with Three-Dimensional Gear Structure, Embedded Tile Design Magic Cube 3x3x3 Puzzles Toys (57mm), Suitable for Brain Development Puzzle Games for Children and Adults --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/18788594-yj-cube-set-4-pack-includes-3x3-fluctuation-angle-mirror](https://www.desertcart.co.uk/products/18788594-yj-cube-set-4-pack-includes-3x3-fluctuation-angle-mirror) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-17*
