BARTH Neutral Bicarbonate Bath Tablets are Japanese onsen-style bath tablets formulated with neutral bicarbonate ingredients. When dissolved in warm water, the tablets release fine carbonated bubbles and create a smooth bathing environment inspired by Japanese hot spring bathing culture.

The tablets dissolve slowly and evenly, allowing the bath water to maintain a consistent composition throughout the soak. Designed as a quasi-drug bath additive in Japan, this product is suitable for daily bathing routines and home spa use.

BARTH bath tablets are individually sealed for freshness and convenience, making them suitable for personal use, short stays, travel, or as a small gift set. The product is manufactured in Japan under quality-controlled production.
