ตะไบเล็บคริสตัล

My nails used to snag on everything until I switched to this tempered glass file, and now the edges are actually smooth instead of ragged. The gentle grit takes a little longer than my old metal one, but it doesn't shred my nails. Been using it a couple months and it still works like day one.

I was skeptical about a glass file, but this thing glides smooth and leaves zero snags on my nails. The grit is gentle enough that it doesn't shred the edges like my old emery boards did.

The tempered glass grit on this file is so gentle it barely feels like it's doing anything, yet my nails come out perfectly smooth with zero snags. I keep it in my purse now and it's held up fine after weeks of use.
