The Best Selling 7 Day Bond & Seal
Salon-quality lashes at home, held in place for days — not hours.

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.

✓ Flexible Finish — moves with your natural lashes, no crunchy feeling

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.
Most customers get a full 5–7 days many go the full 7 or even longer, including through showers, sleep and daily life. The key is prep.
Apply to clean, dry lashes with no moisturiser or oils near the eye area, and always finish with the seal.
That's what makes the difference between 2 days and 7.
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.
With our oil based remover rub the wand back and forth. The bond dissolves and the clusters slide off with no tugging, no pulling, no damage.
Never peel or force them off dry always dissolve first.
After removal, cleanse your natural lashes gently with micellar water add extra remover on top to remove the residue
