Retail Price: 4,378 yen per bottle Purchase Date: February 2025 Purchased from the official website of Kita no Kaitekikobo When used as directed, it definitely tightens the skin around the eyes, but I'm impatient and can't follow the instructions every day (^^;), so I have some left over. I'm listing it now, as it hasn't been long since I purchased it. It's new and unused, but please consider this item only if you understand that it has been stored at home. ☆
