Why Coffin works here
Straight taper to a flat tip — long, angular and editorial. With jet black, the geometry does quiet work: adding intention to minimal color.
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.
- Decide length: shorter wears harder; longer photographs bigger. Match your real week, not your fantasy one.
- Lay down your base coat, then two thin coats of jet black, 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.

FAQs
How do I ask my nail tech for this?

How long does a geometric jet black 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.
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.
Can I DIY geometric jet black 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.
