The first of their kind globally, and scientifically-proven, KURO-Bō Activated Charcoal Kōins are a completely plastic-free, sustainable and recyclable water purification solution.
With our online-only "Buy 4, get 1 Free" deal, up to four people can enjoy naturally purified water on the go every day, and get another 3+ MONTHS completely FREE.
Whether paired with our Glass Water Bottles (550ml or 1L) or your own reusable bottle, a whole pack (4-5 pieces) will purify up to 1L of water at a time.
Activated charcoal, or Binchotan attracts and draws out positively-charged toxins (chemicals, heavy metals, E. coli) from your water, while depositing beneficial minerals and balancing an acidic pH.
