Purchased in Shanghai. Perfect for water purification and interior decoration. This top-quality bamboo charcoal is mainly made by skilled craftsmen who bake it in a traditional earth kiln at high temperatures of 800 to 1000 degrees Celsius or higher (similar to white charcoal). It has a glossy surface and makes a metallic sound when tapped. Please understand that this item has been stored at home for a long time before purchasing. ⭐️I am selling this at a low price due to moving and decluttering. I will only be accepting transactions until March 25th. Thank you for your understanding. Thank you for viewing.
