This is the very popular Lash Addict product!! I purchased it on October 22nd at a lash salon in Sapporo when I got a lash lift. I used it only once, but it didn't agree with my skin, so I'm selling it. Retail price: 11,000 yen The shop staff raved that it makes your lashes grow even longer since the renewal☺︎ Please refrain from purchasing if you are sensitive to used items or home storage! Also, I will include the box as proof of authenticity, but I accidentally opened it, so it's in the condition shown in the photo... Therefore, please purchase only if you understand this!! You can still use it, so please consider purchasing it☺︎
