2-in-1 Dual grit nail dremel bits made for easy nail grinding & polishing
Rougher grit on the outsides for grinding & finer grit on the concave tips for polishing
Unlike sandpaper dremels, diamond grinders stay cooler and won't burn your pet
If they start to lose effectiveness, clean with warm soapy water, rinse and dry well
Size and Grit combinations: Small (80/120); Medium (80/120); Jumbo (60/120, 80/120)
