All our Binchotans are labeled by the Prefecture of Wakayama in Japan and they all bear the yellow certification sticker, as a sign of their authenticity. Beware of counterfeits, 90% of Japanese Binchotan coals from Kishu sold in France are actually made China, Indonesia or Laos. If they do not carry the approval (yellow dot), you are probably dealing with carbons produced outside Japan and activated with chemical solvents. Always ask for the certification label with your Kishu Binchotan coals.


Genuine Japanese Binchotan, 10 gram stick (size S) for gourds

Out of Stock

    A stick of Binchotan, approved for water filtration by the prefecture of Wakayama, usable in water bottles with a maximum capacity of 500 ml.



    1) provide a stick of Binchotan for a gourd with a capacity of 500 ml maximum, preferably in glass (you can reuse a small bottle of fruit juice) or in stainless steel.

    2) make boil the bâtonnet de_cc781905-5cde- 3194-bb3b-136bad5cf58d_charcoal for 15 minutes in a pan of water before using

    3 ) take it  out of the water and let it  dry for about 15 minutes.

    4) insert the bâtonnet into the bottle

    5) let the charcoal act for 8 hours.


    The ideal is therefore to start the night before and let it act for a whole nuit. You can use them everywhere: at home, at work, when traveling abroad

    An activated carbon stick is economical because it is used for 6 months. It is also ecological because it avoids the massive use of mineral water bottles and plastic filter jugs.

    Each month, all you need to do is purify your coal  by boiling it again in a pot of water for 15 minutes.

    Beyond 6 months, the carbon being saturated, it will be necessary to change it.

    It is recommended not to leave a charcoal in the same water for more than 48 hours. If this is the case, all you have to do is empty the water and let the charcoal act again for  8 h.


    What to do with used coals? 

    Do not throw away your used coals! They can still be used to reduce odors in the refrigerator or shoe cabinets. You can also  use them for decoration (some make pretty  chimes  or xylophones_ cc781905-5cde-3194-bb3b-136bad5cf58d_thanks to their sound_cc781905 -5cde-3194-bb3b-136bad5cf58d_metallic). You can also  put them in  the barbecue (it is a very slow burning wood, which will release little_cc7 81905-5cde-3194-bb3b -136bad5cf58d_ smoke or smells), or compost it. 

    Binchotan is totally recyclable!
