Thank you for viewing. This is Domohorn Wrinkle "Night Care Collagen" drink. If you purchase it normally, it costs 432 yen per bottle, and 4320 yen for 10 bottles, so I think it's a great deal. It's new, unopened, and a fresh item that just arrived. During this dry season, and also when your skin is unstable, how about achieving beautiful skin from within, hydration, and high-quality sleep? This is a set of 1 pack (10 bottles). The expiration date is June 2026. * For more details, please refer to the Domohorn Wrinkle official website. Shipping and handling fees will be charged, so I am offering it at a very low price. Therefore, I am sorry, but I cannot offer a discount. Due to the thickness, I cannot ship it in the box, so I will wrap the 10 drinks in bubble wrap to prevent breakage and ship them in a Yu-Packet Plus box. If you have any questions, please feel free to comment.
