I bit my nails for twenty years.
When I want to bite, I paint a coat instead. Six weeks later they are past my fingertips for the first time.

The Signature Pen · Keratin Length
Your nails grow, they just break first. Seal the tip and keep your own long nails, no press-ons.
No polish can change how fast a nail grows. It protects the tip, where nails snag and break, so the length you grow stays on.
No glue, nothing stuck on top. These are your own nails, kept long because the tip stops breaking.
With your usual nail polish remover. No soaking, no scraping.

How it works
Nails break at the free edge. Each coat wraps the tip in a keratin-enriched layer, so the length stays on.
Six weeks, same hand



K-BEAUTY INNOVATION
In Korea, nail care is treated like skin care: color is expected to protect, not just decorate. The keratin-enriched formula behind The Signature Pen comes from that Korean innovation, now in a pen you can use at home.

Press-ons wrecked my nails. Now my own nails are long and even, no glue, no salon.

One broke, I cut them all, every month. With the tips sealed they finally grow out even.
