All of LashedByE's Premium Mink Eyelash Extensions are handmade insuring quality and consistency. All lash trays include 12 strips with approximately 2,000- 3,000 lashes per tray. The unique sticky lash strip will prevent the volume fans from separating at the base, allowing you to create the perfect fan within seconds. Each row comes on a sticker that can be put on your work area so you can work efficiently, and more quickly.
