KALDI Serum Concentrate Facial Serum 20ml 1 bottle, 13,200 yen (tax included) Purchased December 2023 This is a concentrate (intensive) wrinkle serum that gives the skin firmness and elasticity. I bought it as a courtesy, but I still have some in stock, so I'm listing a new one. Although it is new, it has been stored at home by a private individual, so please refrain from purchasing if you are sensitive to this.
