These are a must-have in the eyelash-extension industry! Fantastic for cleaning the lashes at the start AND for applying the cream/gem eyelash extension remover when removing one or multiple lash extensions!
You can sell a few of these with your business card for $5 for the client to clean their lashes at home with, or simply do what I do and offer for free with their appointment. I often use this wand on my clients DURING lashing and give to them at the end. It adds a touch of class, sparkle and the "i received a present from my eyelash technician!" feel.
You can certainly add other products such as shampoo, your lash care instructions, a wash brush and bump up the price to $10-$30 depending on wat you choose in your lash-package.
