Staleks Pro Beveled Straight Plastic Nail File (Base), Lightweight Professional Use Expert 20, SPBE-20

Pros:Snug fit compared to the metal version.Has an added thickness on one side so it can be more comfortable to hold.Lightweight.Cons:Since it is plastic, do NOT keep it anywhere near monomer or acetone. It will warp and melt 😭.Since only one side it flat, you cannot use the dual sided slips.. if you can find those at the moment. I prefer the double sided file slips but I could only find the single sided version at times of purchasing.I have not tried the Sticky disposable files with this one, just the ones that easily slip on and off.
