Once you try this adhesive, you will wonder why you haven’t tried it sooner. This is a quick drying, low fume adhesive that has a very long shelf life! I have even tested it myself and retention & consistency did not change even after 3 months from opening. This adhesive is also tolerable to a wider range of humidity and temperature than most adhesives on the market, so it’s great for artist who do house calls or even when the climate in your area is not consistent throughout the year. Lastly, this adhesive is BLACK. All my clients noticed the switch without me telling them because their lash line looked so much darker. I have already gone through a dozen of these and the quality never disappoints and stays consistent. I’m in love with [****]!
