Review on 🔧 MAKARTT Nail File Kit Set - 100 180 Grit Double Sided Black Washable Files for Acrylic Nails, Poly Nail Gel - 10-Piece Nail Accessories Manicure Tools (F-01) by Patricia Muller

As another reviewer mentioned I would like to read the description more closely. I bought 100/180 when I should have bought 180/240. 100/180 is pretty harsh, I think it will work for acrylic nails and maybe pet nails. My nails are neither weak nor too thick. This sand is too much for my nails. I've used them on toenails which tend to be thicker. I'm planning to try this on my cat's claws, LOL if I may! I can't tell the difference between the cereals, maybe it's just me, but they seem to be the same. I'm fine with my purchase, I might even find other uses for them around the house (I tend to repeat things that don't work as intended).
