I purchased and used this around April. (Used about 4 times a week) I'm not sure how much is left, but the eyelash technician said there was enough to last for six months. I can visually confirm that the tip is wet. This is an authentic product purchased at a salon. The label is peeling, so I've marked it as having some scratches and dirt. I'm selling it because I bought a new one. *Box not included. Retail price was 11,000 yen.
