I ordered these as well as custom brass knuckles to fit together. The seller was very nice, communicated well, and worked very quickly. They even included a nice gift 💖. The pieces are nice. They layering is thick so you can tell that they are 3d printed. A bit of sanding could help with that if you know what you're doing. I don't mind so much and planned on customizing them further anyway. The joycons fits in the knifes very nice and pops out with little problem. There's a bit of a wiggle to the knives but there are ways to make them more snug. The brass knuckles are nice though their pattern is the same so one of them has to go on backwards. Overall a fun product.
