nail sanding blocks,
Verified Purchase(What is this?)
This review is from: The White Sanding Block 100/100 4 sided - 2006701 + 100 Lint Free Nail Wipes by Boolavard® TM (Misc.)
Use these before gel polish. Thought there were more than one because of advert picture but should have read description in more detail. They do the job they are meant for.
