The Best Selling 7 Day Bond & Seal
Salon-quality lashes at home, held in place for days — not hours.
Our Bond & Seal is a two-step system designed specifically for cluster lashes. The Bond grips your clusters securely. The Seal locks everything in place and protects against water, oil, and daily life.
Together they give you a clean, flexible hold that lasts up to 7 days without stiffness, heaviness, or irritation.
No salon appointment. No harsh chemicals. Just lashes that actually stay put.
What Makes It Different
✓ 5–7 Day Hold — long-lasting wear designed for real life
✓ Shower & Sweat Proof — holds through daily routines without lifting
✓ Flexible Finish — moves with your natural lashes, no crunchy feeling
✓ Oil Resistant — works with your skin, not against it
✓ Cyanoacrylate-Free — no harsh chemicals, no stinging, no reactions
✓ Latex & Formaldehyde Free — gentle enough for sensitive eyes

How to apply bond and seal
Frequently Asked Questions
No not when removed correctly. Our bond is designed to release cleanly with our dedicated remover, with zero pulling on your natural lashes.
The only time damage happens is when clusters are forced or peeled off dry.
Dissolve the bond first, the clusters slide off, and your natural lashes are completely untouched.
Make sure you don't use any oil based products before applying this include makeup wipes, oil face cleansers, moisturisers.
Lashes should be full clean and dry.
When getting your makeup off around the eyes use a wet flannel and an water based cleaner, then use micellar water on a cotton bud (pink top) to maintain daily.
Yes. Our formula is latex free, formaldehyde- free and cyanoacrylate free that last one is the harsh chemical found in most lash glues that causes stinging, redness and reactions.
It's designed for everyday wear, even on sensitive eyes. We still recommend a patch test 24 hours before your first use, just to be safe.
Both have exactly the same hold strength it's purely about the finish you want. Black gives you a defined lash line effect, best for pros.
White dries completely clear and invisible perfect for a natural, seamless look. Best for beginners.
Both formulas are the same.
Not sure? Go white. You can always build more definition with the black later.
Most lash glue goes hard and stiff once it dries. That sounds strong. But stiff glue cracks easily.
Every time you blink, rub your eyes, or sleep on your side, that crack gets a little bigger. Soon your lashes start to lift.
Our formula stays soft and flexible after it dries. It bends when your natural lash moves, instead of fighting against it. No cracks. No early lift off.
Then the Seal goes on top. Think of it like a raincoat for your lashes. It blocks out water, sweat, and oils from your skin the three things that break glue down fast.
Two steps. Two jobs.
The Bond holds your lashes on.
The Seal keeps them protected.
That's why Bond & Seal lasts 5 to 7 days, not 1 to 2.
Cyanoacrylate is the fast curing chemical in most lash glues, and it's also the most common cause of stinging, redness, and reactions, because it releases fumes as it cures.
We use an acrylic resin base instead, which bonds just as securely but cures without the irritation.
If you've ever had a lash glue make your eyes water on application, that's almost always the cyanoacrylate not "sensitive eyes."
