ITS GREAT GLUE AND HOLDS WELL, BUT I AM ALERGIC TO IT. I NEVER USED TO BE. MY EYELIDS SWELL AND TURN RED AND ARE VERY SENSITIVE NOW. I CLEANED IF OFF VERY WELL BEFORE BED. I HAVE USED THIS BRAND IN THE PAST WITH NO ISSUES. I EILL STILL USE IT FOR SPECIAL OUTINGS BECAUSE I MISS WEARING LASHES I HAVE WORN THEM FOR ALMOST 6 DECADES. IT IS MY ISSUE. I AM JUST SAYING IT COULD HAPPEN IF YOU ARE ALLERGIC TO ADHEDSIVES, AND MAGNETIC GLUE AS WELL. I WOULD RATE THIS 5 STARS FOR MOST WEARERS. IT IS VERY NICE.
