At .07 these lashes are thin and lightweight for those who like to "stack" lashes for the Volume effect. Soft and more subtle than the conventional Synthetic Mink lashes, these are a great lash for those looking for a fuller look and a softer feel. With just a "touch" of glue used at the base you can apply 3,4,5 or more of these lashes to the base of the natural lash and its still lighter than a .20mm lash. (5) .07mm Lashes are the same weight as (1) .20mm lash so stacking the lashes is not adding any weight. Assorted Lengths in the case are 6,8,10,11,12,13,14 mm.
