This has to be the best lash bond I've ever had. The lashes last me easily 2 weeks, I doubled my application so I'll probably try the Superstar set next to see if I can use just one. At first I was treating it like the usual lash kits by washing around them with a cloth but I took a leap of faith and dunked my in water and it stayed! I'm attempting to wash the lashes to reuse now but I will be ordering a fresh set. Amazing product!
