Thank you for viewing. Lash Addict Lash Conditioning Serum 5ml Purchased one year ago, opened two months ago. I didn't use it every day, so there's still a lot left, enough that you can hear it slosh when you shake it. I threw away the box, but the manufacturing number is clearly written on the product. I purchased it at an eyelash perm salon. Would you like to try it? I will wrap it in bubble wrap for packaging. Thank you.
