Review on 🔪 Onsen Japanese Nail File - Professional 6-Pack Nail Files: Natural & Acrylic Filers for Salon Smooth, Shiny Nails - 120/180 Grit - Disposable, Travel-Friendly by Valerie Jones

So far I like these files. I've only used them a couple of times and use them on my natural nails. There must be dirt on it. Always try to file your nails in one direction to avoid tearing the nails. Having only used them a couple of times I'm not sure how they will hold up. They seem well built and I love their size so I'm optimistic about their durability. They are exactly as described by the seller and were delivered very timely. Since you have 10 of them, I find them very economical and you can have them with you everywhere (in different rooms, handbag, bathroom) so you don't have to look for them all the time.
