Starlit Love — Long coffin nails in a translucent smoky grey-taupe, cut with sharp black angular tips. Accent nails carry pearlescent white heart cabochons outlined in tiny rhinestones, plus small black star shapes scattered across the surface.
The base is see-through rather than solid, so the black tips read as graphic blocks floating over your own nail. Hearts and stars on a smoke-grey base give the set a Y2K edge — it is the darkest design in the range without being an all-black set.

FIG. 04 Gentle removal — take your time
- Soak your nails in warm water and mild soap for 10–15 minutes to loosen the adhesive.
- Starting at one side, gently lift with the included cuticle pusher — never force or pry a nail free.
- If a nail resists, dab a little cuticle oil at the edge and let it sit for a minute before trying again.
- Once every nail is off, buff away any leftover adhesive and finish with cuticle oil or hand cream to hydrate your natural nails.
