Lightful UV Blue Adhesive

Lightful UV Blue doesn't cure on humidity. It cures on light. Place the fan. Adjust it. Adjust it again. Nothing is happening until the light hits it — and then it's set in half a second. No humidity math, no flashing before placement, no premades fusing into a strip because they touched each other in the tray. It's a transparent blue in the bottle — easy to see on your tile, not noticeably blue on lashes. Requires a 395–405nm UV-LED lamp. If you don't have a compatible lamp, get the Lightful System kit instead (coming soon).
