They sent the wrong product.

I am extremely disappointed with this seller.

First, they marked my order as “shipped,” but in reality, it was never sent. When I checked the tracking, there was no movement at all. When I contacted them, they first said the package was “lost,” which already raised concerns.

After that, they apologized and promised to resend the order. I waited a long time again, and finally received a package — but guess what? It was the WRONG product.

This has been a complete waste of time. The communication is inconsistent, and the information they provide is unreliable.

Be careful when ordering from this seller. Either they don’t ship your order at all, or they send the wrong items.

Very unprofessional experience.

The best file ever

I’ve used many files, and this one delivers. The grit is well-balanced, durable, and gentle on the natural nail while still being effective. It holds its shape and gives precise results. Definitely a solid choice for both pros and serious at-home users

The healthy nail tincture was prescribed by my podiatrist. I’ve been using it for 3 months and my mail is almost completely clear of the fungus. I would recommend it.
