The classic OPI Top Coat. Standard glossy finish that goes over any nail color (OPI or other brands) to build long-lasting wear by sealing in color and providing a hard, shiny surface that resists chips and scuffs. The baseline option in the OPI top coat lineup — reliable, predictable, neutral high-gloss.

For Korean shoppers comparing OPI top coats: if you want a different finish (matte, mirror, gel-like), see Matte (NTT35), Mirror Shine (NTT37), or Plumping (NTT36). If you want speed, see RapiDry (NTT74). If you want maximum durability with a base coat included, see Infinite Shine Duo (IS-DUO). The classic Top Coat is the starting point — everything else is a specialty.

How to Use
  1. Apply OPI Nail Lacquer color (2 thin coats), allow each coat to dry.
  2. Wait 1-2 minutes after final color coat for color to set.
  3. Apply 1 thin coat of OPI Top Coat over the entire nail.
  4. Cap the free edge of the nail (drag the brush along the tip) to seal in color.
  5. Allow 2-3 minutes to dry. Avoid touching anything for the first 60 seconds.
  6. Reapply Top Coat every 2-3 days to extend wear.
Tips From Pro Nail Artists
Don't apply Top Coat too thick — it will take longer to dry and can cause smudging in the color underneath. Two thin coats are better than one thick one.
Capping the free edge (the tip of the nail) with Top Coat is the single most important durability step. Without it, color chips from the edge inward — most manicure failure starts at the tip.
The classic Top Coat is the most versatile option — works under or over other OPI top coats. Use Top Coat alone for standard manicures, or layer with Mirror Shine on top for extra reflective depth.

FAQ
Q: How is this different from Matte Top Coat?
Same role (sealing polish), different finish. This is high-gloss; Matte Top Coat (NTT35) gives a flat matte finish over the same color.
Q: How is this different from Mirror Shine?
This is standard high-gloss. Mirror Shine (NTT37) is the premium-tier option with noticeably more reflective finish. Choose Mirror Shine if you want maximum gloss; choose this for everyday reliable shine.
Q: Does this work over gel polish?
No — this is designed for regular nail lacquer. Gel polishes need their own top coat cured with UV/LED lamp.
Q: Can I use this over Nail Envy?
Yes — Nail Envy variants (including the colored Strength + Color line) can wear a top coat over them for extra gloss and durability. The Nail Envy strengthening cycle still works underneath.
Q: Is this the authentic OPI product?
Yes. Sourced directly from authorized US nail-supply distribution. We do not re-package, re-bottle, or source from grey markets.
Q: Is it new and unopened?
Yes. Every bottle ships factory-sealed in original retail packaging.
Q: How long does shipping take?
Orders are dispatched within 1 to 2 business days. International transit to Korea typically takes 7 to 14 days depending on customs clearance.
Q: Can I cancel my order?
Orders can be cancelled before dispatch — usually within 24 hours of placement. Once shipped, cancellations are no longer possible.
