I purchased this from the official Amazon shop. I tried it once on my fingernails, but it doesn't seem to work the way I envisioned, so I'm letting it go (><) The sharpness is almost unchanged, but it is considered a used item. Would anyone like to try it out? I have washed it with water and dried it. I will pack it with bubble wrap before shipping. - Model Name: Ultimate Nail Clipper - Country of Manufacture: Japan - Design: Winter Design - Size: M
