Our lashes are made from a polished, synthetic material and are the firmest/sturdiest of all. They are meant to mimic real mink lashes without animal cruelty or the worry of allergic reactions to animal fur. In appearance, they are a little shinier or glossier. When applied, they are quite thick and dramatic. They come in a wide variety of thicknesses and curls, and can be applied to look very natural or dramatic. They hold their curl extremely well due to their firmness. Lengths from 8mm - 14mm in each tray.
