From Natural everyday lashes, to those High-Fashion shots...there are lashes for every occassion. Pricing for a set of false lashes can vary from $2.50 to $350.00 and more.
Tools you need when working with lashes:
Lash Adhesive (my favorite is Duo - Dark Tone)
Eye makeup remover
Storage box (usually comes with lashes)
