MEDULLA HYPERLINK SERUM, made in Japan, is a serum that moisturizes hair and supports styling. - Brand: MEDULLA - Product Name: HYPERLINK SERUM - Country of Manufacture: Japan I've used it for 10 pumps. Please refrain from purchasing if you want an unopened item. Price is not negotiable. Thank you for looking.
