New, unused, and unopened! Thank you very much. AiRevo Human Stem Cell Serum, set of 2 Regular price per bottle: 21,000 yen (excluding tax) Ingredients: Human stem cells Type: Bottle I have a large surplus of Letter Pack shipping materials and would like to use them up. I would appreciate it if you could cooperate by changing the shipping method to Letter Pack. If you're okay with Letter Pack, please comment. I will discount the price by 210 yen. If you prefer Rakuraku Mercari delivery, please purchase as is. (Generally, purchases without comments are welcome, but if there are comments regarding Letter Pack, etc., those will be prioritized.)
