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 matte 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.

Can I DIY long matte cobalt nails at home?
Absolutely. Striping brushes, dotting tools and sheer patience cover 90% of these looks; the rest are one salon visit away. At-home gels have never been more beginner-proof.
Is a coffin shape practical for typing?
A longer coffin asks for some adaptation — many people keep their dominant hand shorter or choose medium lengths for keyboard-heavy weeks.
