Kikiyu 黏土小蘇打碳酸熱水入浴劑補充包（480g）x 2 + 1

My skin has felt noticeably smoother since I started using these refill packs, and I love how the carbonation makes the bath water feel silky. The 480g size lasts me a good while, so it's great value.

The carbon dioxide fizz in the bath really makes the water feel different—almost spa-like. My rough patches on my elbows have softened noticeably after just a few soaks. For the price of three refills, this is fantastic value.

My skin's been less itchy since I started using these, and the carbon dioxide bubbles really do create that hot-spring feel. A single 480g refill bag lasts me over a month, so this two-plus-one set is solid value.
