The pen itself is simple. The results come from the part nobody sells you: using it every single day. Here's both halves.
Using the pen
1) Start with a clean, completely dry nail. 2) Twist or press to load the brush tip. 3) Paint a thin layer across the whole nail — edges, ridges, and the line where nail meets skin. 4) Let it dry for a minute before socks or shoes. That's it — under a minute per session.
Sticking with it
Anchor it to something you already do daily (after brushing teeth works). Keep it visible — bathroom shelf, not a drawer. Track honestly: photo every two weeks; look at new growth near the base, not the old damage at the tip. Size the supply: the 4-count set exists so you don't run out mid-cycle — an empty pen in week three is how routines die.
