I have the most sensitive eyes and have tried every glue there was. This is the ONLY glue that doesn’t make my eyes water or puffy. The clusters were on for three days! I slept on my face, washed it, got caught in the rain and they didn’t budge. Honestly forgot I had them on! I only removed them to try a longer length lol! They come off easily with micellar water. Best cluster set ever, and the tweezers are luxurious. I’m obsessed and feel like a pro doing my own hair, nails and now lashes.
