Very aggressive grit
Most of us don't know what 100 grit and 60 grit equates to, but when you handle these nail blocks you quickly figure out that both of them are COARSE grits. For many people they will be TOO coarse and will leave nails rough and scraped-looking.  They may work better for tough nails like on the toes, or for tough fake nails, but for buffing and gentle shaping of fingernails, a less aggressive file or block would be preferable.<br /><br />I may end up using these in my workshop!
