Actually useless the rings are too big at the back of the tools and there is no way I puncture a pimple with the drill sized heads

I expected it to be cheap, but I thought it would serve many other purposes as a tool. In the end, it is precise, very sharp, and effective, especially the angled part. Tip: because it cuts the skin and leaves a mark, if you don't hit the exact spot, it's better not to do it on your own but have someone else do it for you
