This is OPI's take on cobalt blue: F018 Y2Slay, with a glossy finish. Blue is high contrast against most skin tones, so a clean cuticle line matters. It is carried in the fall gel lacquer line-up at ND.
What you get in the bottle
- A formula techs already know: GelColor has run in salons since 2011, which means no relearning the application on a busy day.
- Gel and lacquer that agree: both bottles are mixed to the same shade so the take-home matches the set.
- Three weeks between fills: with proper prep and a capped free edge the colour holds for about three weeks.
- No animal-derived ingredients: the formula is vegan across the OPI range.

Picking the right option on this page
On this page you are choosing between OPI F018 Y2Slay in different formats. Gel Polish & Lacquer is the matched gel and lacquer pair, so the client can take the polish home in the same shade. Gel Polish Only is the gel bottle on its own, for salons that only run gel services. Nail Lacquer Only is the air-dry lacquer on its own, no lamp needed. Dipping Powder is the matching dip powder for a dip service in the same shade. Think about who is buying. A mobile tech carries the OPI F018 Y2Slay duo and nothing else. A salon with three stations and a dip menu is better served by the combined option.
If the set lifts early
Early lifting is almost always prep rather than the colour, and that holds for OPI F018 Y2Slay as much as any shade on the wall. Make sure the shine is fully off the plate, the cuticle is pushed back and the surface is dehydrated before the base goes on. Keep every layer thin and cap the free edge on the base, both colour coats and the top. A thick colour coat is the most common cause of a set that peels at the stress point in week two.
OPI F018 Y2Slay is stocked alongside every OPI shade ND carries, the fall gel lacquer line-up and the OPI lacquer range.
