Why Coffin works here
Straight taper to a flat tip — long, angular and editorial. With cobalt, the silhouette does quiet work: making art read larger, while the long length keeps it dramatic without entering high-maintenance territory.
How to get the look
- Prep: remove old polish, soak off any gel properly, and shape into coffin with a glass file in one direction.
- Push back cuticles gently — never cut — and wipe each nail with isopropyl or a dehydrator so base coat actually grips.
- Choose long tips or keep natural length conservative; maximum canvas for art, maximum main-character energy.
- Lay down your base coat, then two thin coats of cobalt, capping the free edge each time — capped edges are the anti-chip secret nobody markets.
- Add the geometric work in thin layers. Thin layers cure fully; thick ones wrinkle, bubble and lift within days.
- Seal everything with a quality top coat along the edge, oil your cuticles, and give hard tasks 24 hours before full wear.
