Purchased in September at Ainz & Tulpe and used for about a month, with some days in between. I experienced pigmentation, making it difficult to use daily, so I am selling it. When shaken, you can clearly hear the sound of water, so I believe about half the product remains. However, as the remaining amount is not visible, please purchase at your own discretion. There is no outer box. I will wrap it in bubble wrap and ship it via Yuu Yuu Mercari delivery. Instant purchase is welcome. Price negotiations are not accepted.
