Dũa móng tay

The fine-grit side leaves my nails feeling like glass, no need to buff afterward. I keep one in my purse and one at my desk since it's so light, and the dual grits handle everything from a snag to a final shape.

The coarse side files down a rough edge in just a few swipes, and the finer side leaves my nails feeling glassy without any harsh scraping. It’s thin enough to toss in my purse, which honestly makes it my go-to between manicures.

The dual-grit side is perfect for smoothing edges after I've cut my nails too short. It shapes without tearing or snagging, unlike some cheaper files I've used.
