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 duo-chrome 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.

FAQs
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.
What skin tones suit cobalt best?
Cobalt reads beautiful across undertones — cool undertones can lean into its crisper register, warm undertones into its deeper side. When in doubt, test on one nail in daylight.
How long does a long duo-chrome cobalt nails set last?
With a dehydrator, quality base coat and capped edges, expect 10–14 days from gel and 5–7 from regular lacquer. Press-on versions typically hold 1–2 weeks with glue.
