How to Get the Most Out of Your Strong and Hard Professional Jumbo Nail Files

If you’re using the Strong and Hard Professional Jumbo Nail Files for the first time, here’s how to make them work for you. Each file has 80 grit on one side—perfect for shaping acrylics or reducing thickness. The 100 grit side smooths the surface and refines edges for a clean, professional finish.

Start by using the coarse side to shape extensions or remove excess product. Switch to the finer side to blend and prep for polish or gel. Always file in one direction to avoid damage, and clean the file with soap and water after each use.

Thanks to their hardboard core, these files won’t bend, giving you control every time. With 25 files in a $18.00 pack, you can use them in rotation or keep separate ones for different clients. Easy to use, even easier to love.
