These files are good for the price and get the job done. They work fine for acrylic or dip nails! The rounded corners are perfect, I just need a more sturdy file. I would recommend them if you’re on a tight budget and need a “good enough” file!Would buy againLove these definitely my go toGreat product for gel nails, toe nails, rough heals and my dog’s nails too! Shared with friends and family and everyone has liked this product :)Use them dailyDef worth the price if your looking for a tougher grit file!These double sided emery boards are such a great value for your money. The only issue I had with these which was kinda a good and a bad thing, was how stiff they were and if you are not careful you will get some skin. But, as you know, the best thing to do in cases like this is to soften the edges with another file that way it is not so rough on your own nail.
