BARTH is a neutral bicarbonate bath additive created using unique manufacturing technology. By making the water neutral, the bicarbonate ions generated from the carbon dioxide gas are less likely to evaporate, dissolving thoroughly into the water and maintaining their concentration for a long time. The active ingredients enhance the warming bath effect and promote fatigue recovery. Furthermore, rinsing removes dirt and gently cares for the skin. - Brand: BARTH - Product Name: RECOVERY & TREATMENT - Contents: 15g x 30 tablets (10 uses) - How to Use: Use as a bath additive - Features: Neutral bicarbonate bath additive This was a gift, but I am selling it because I don't use it.
