Bonds with nails so they can withstand wear and tear.

Works to reduce brittleness and prevent broken fingernails. Hard Top also addresses the issue of nail-biting, because treated nails become literally too hard to be bitten. Additionally, it takes the palce of formaldehyde-type basecoats, serving as a primer.

Apply to bare nail several times daily, or can be used as a primer prior to applying polish. Do not apply over polish will cause smearing.
