I've used about half of the Needle Shot 100. I've also used about half of the pack. I used tweezers to handle them, so I haven't touched them directly. I apologize that they've been used, but people around me say that using this set gave them incredibly beautiful skin! It didn't suit my skin, so I'd like someone else to use them. I'll also include some free samples. Thank you! Beautiful skin Brightening UV rays UV Skincare
