Dũa móng tay thủy tinh

Glass files always felt gimmicky to me, but this one actually redefines the edge instead of scraping it. The surface is so fine I can shape my nails without any of that harsh grating sound, and it never wears down no matter how often I use it.

I’ve been using it for two weeks now and my nails have never looked this clean—the glass surface files so smoothly that there’s zero peeling, and it rinses off in a second. Definitely worth it for the reusable aspect alone, no more tossing out worn-out files every month.

The grit is so fine that it glides instead of scraping, and my nails haven't felt this smooth after filing in ages. I've used it three times this week and it still works perfectly, which is way better than the disposable boards I kept replacing.
