I call it feather lash extensions . It’s for gals who are very keen on full/large volume looking extensions but don’t have enough own lashes. Its thickness is 0.07mm (half thin as the normal thinest lashes) so it’s super light that I could put 2 to 3 pieces on your each own lash to make it full. $100 for the fullset feather lashes ! Welcome to book to try!
