Review on 💎 COMOWARE Precision Polymer Jewelry - 0.3mm/3mm by Caleb Quade

These worked fine. There are only 2 complaints, one minor and one fairly major. Small complaint that I had to use a micrometer to measure each bit because they just came in little plastic bags with no labels. The big problem is that the cartridge was very difficult to use. The threads for tightening were narrower and it was almost impossible to hold the body, tighten the nut and hold the bit in place so it could be tightened. Had the threads been trimmed properly it would have gotten 5 stars.
