While there are quite a few counterfeits circulating, this is a genuine, authentic product. Completely unopened (with serial number) Shipped in a box for peace of mind. Esthe Pro Labo Herbzyme Plain, set of 2 Expiration date: September 2027 ¥10,800 x 2 = ¥21,600 A large quantity arrives monthly via a subscription for my family, but we often can't finish it all, so we have leftovers. I am selling the most recently arrived items. This is already a significant loss for me, so please refrain from price negotiations. Thank you very much (*^^*) Supplement form: Liquid
