1. Shake thoroughly before use.
2. Dispense a fresh adhesive drop.
3. Dip approximately 1–3 mm of the extension base into the adhesive.
4. Isolate first, then place the extension directly onto the natural lash without unnecessary repositioning. Sky recommends clean natural lashes and decisive placement for stronger attachment.

• Using an old glue drop → Replace it when the consistency begins to change.
• Dragging adhesive off the extension → Dip cleanly instead of wiping the lash against the glue surface.
• Repositioning repeatedly → Place decisively once the extension contacts the natural lash.
• Ignoring humidity → Monitor your room conditions throughout the service.
• Applying over residue or buildup → Clean the natural lashes thoroughly before application.

Is Sky Black Cap suitable for beginners?

Its 2–3 second bond time provides more working time than very fast adhesives, but it is still intended for trained professional lash technicians.

Can I use Sky Black Cap for Classic and Volume lashes?

Sky adhesives are designed for professional individual lash application. Technique and adhesive pickup should be adjusted according to the lash style being created.

Why is my Sky adhesive curing faster than usual?

Higher humidity accelerates cyanoacrylate curing, so changes in your room environment can noticeably change adhesive speed.

Why is my retention shorter than expected?

Humidity, lash cleanliness, adhesive freshness, attachment technique, and repositioning after placement can all affect retention.

How should I store the bottle after opening?

Keep it tightly closed, upright, cool and dry, preferably inside an airtight container with silica gel.
