5 Pack (5 x 15ml) INK 007 - Acid free Bond! Designed to be an all-in-one bonder for use with iLac, xLac, Acrylink and iJel. INK 007 works by firstly penetrating and clearing the ridges of the nail plate eliminating any dirt, grease or oils before filling said ridges with a tiny amount of gel before leaving the surface area tacky...it keys into the nail plate before adhering to your chosen product. INK 007 must be used sparingly‚ the idea is to only just cover the nail plate/tip and not to build upon it thin to win! This kind of product needs quite a short brush, not to wide, not to thin, not too many hairs, not too few‚ as you paint you need to feel a little resistance, a slight bend in the brush without it surrendering completely giving you, the pro, complete control over its movement‚ The brush is Perfect!!! ***Acid Free*** ***Apply thinly - Air Drying in 60 seconds whilst maintaining a sticky layer.
