Anyone wanting easy salon-quality lashes
Three steps. Ten minutes.
No technician required — just a steady hand and a mirror.

Lock everything in with our seal coat for a flawless finish that lasts up to 7 days.
What map fits your eyes?
Every eye shape gets a slightly different length sequence — here's ours.
Almond Eyes
Enhances your naturally balanced eye shape with a soft, elongated finish.
Round Eyes
Adds length to create a more lifted, elongated appearance.
Small Eyes
Creates subtle definition without overwhelming smaller eye shapes.
Hooded Eyes
Designed to create the appearance of lift and open up the eye area.
Downturned Eyes
Helps create a lifted effect at the outer corners for a more elevated look.
Cluster, strip, or full set?
There are three ways to wear false lashes. Here's how ours — clusters — are different.
One band, one motion
One long strip of lashes glued on in one piece. It goes on fast, but it comes off every night.
Small groups, placed by hand
Small groups of 3–6 lashes, glued on one at a time under your lash line. You choose how full it looks, and it can last for days.
One lash, one lash, by a pro
Single lashes glued onto each of your own. A pro does this in a salon — it looks the most natural and lasts the longest. But real extension glue is chemically strong, so your own lashes can snap if they're removed the wrong way.
C curl, D curl — decoded
Curl is the shape of the lash. Effect is how many hairs are in each cluster.
Natural, gentle lift
A soft curve. It lifts your eyes a little without changing your natural lash look much. More natural-looking than a D curl.
Bold, wide-eyed curl
A deeper curve that curls back more. It opens your eyes wide — this is the "doll eye" look.
Effect is how many fibres per cluster. Natural (2–3 hairs) is soft and simple, like SL26, SL22 and SL25. Hybrid (4–5 hairs, like SL01, SL02, SL04 and SL27 — and this SL03) mixes soft and full. Russian Volume (6+ hairs, like SL17, SL18 and SL20) is full and fluffy.
A full set in under 10 minutes
Here's what happens at each step.
Prep — Clean, dry, oil-free
Clean your lashes and let them dry all the way. Oil is the number one reason glue won't stick.
Map & Place — 5–8 clusters per eye
Depending on your style and eye shape. Using your lash map, place each cluster right on your lash line — never on the skin — about 1mm above the root.
Bond & Clamp — apply, wait 20 seconds, then place
Apply Bond onto your natural lashes only, then wait 20 seconds. Press the cluster onto 2–3 of your own lashes, then clamp — gently squeeze the cluster and lash together so the glue sets in place.
Seal — locks in under 60 seconds
Apply a thin layer of Seal underneath the cluster, and on top at the roots too. It locks everything in and dries in under a minute.
Step 5 · Cure — full strength develops over 24 hours
It feels dry fast, but the bond keeps getting stronger for 24 hours. Skip water and steam during that time. A full set takes under 10 minutes — pre-glued lashes take just 5.
The finer details
Bond & Seal, reuse, safety and cost — everything else worth knowing.
Made for one job, not clusters
Weaker, and can't bend around small clusters — it mostly holds for about a day before clusters crack and fall off.
A soft wrap, not a hard line
Bond dries naturally soft, so it moves with your natural lashes instead of damaging them. Seal blocks out water and sweat, so nothing peels off.
4–5 full sets per pack
You can wear each cluster more than once. Clean each cluster and wear it again, up to 2 times — it stays good if stored clean and dry, away from sun and Bond/Seal.
1–2 reuses per cluster
Each cluster can be cleaned and worn again. That's 4–5 full sets from a 40pc pack, or 8–10 from an 80pc pack.
Patch test first
Put a small dot of Bond on your inner arm or behind your ear. Wait 24 hours. If you see redness, itching or swelling, don't use it near your eyes.
Store them right
After you remove a set, gently clean off any old glue. Let clusters dry fully, flat, out of direct sun. Keep them away from any leftover Bond or Seal.
Every eye is different — use this as a starting point, not a rule.
Start with your shortest map (like our SL26) or a more forgiving length — you can always build up.
Start with our Starter Kit (SL22) — a more forgiving length and step-by-step guidance.
See how they wear it
Real women. Real results. No filters needed.
Loved by thousands of women
Called them a game-changer with an amazing curl, not too long, and said people keep asking if she'd had extensions done.
Struggled to apply lashes before finding Sultry — says the band sticks on well and the beauty blenders, cut in half, make under-eye application much easier.
An eight-year lash extension wearer called these the best clusters she's tried, giving that fresh-from-the-salon look.
Customers consistently highlight the lightweight comfort, easy application, and long wear of Sultry's cluster and strip lashes — many say they've been mistaken for salon extensions, with wear reported anywhere from 5 to 14 days.
