I only tried them on twice. I'm selling them because they didn't suit my eye shape. I really want to recommend them to those who they do fit, as they're so easy to apply (T-T) They originally cost nearly 5000 yen, so this is a great opportunity to try them at a lower price. These are highly safe false eyelashes using R-SLM™ technology, and are easily applied in 4 steps. - Technology: R-SLM™ - Box Design: Integrated box - Included: Eyelashes and tweezers - Application Steps: 4 steps - Safety: High safety Thank you for looking.
