Thank you for viewing. This is wood ash from my home's wood-burning stove. It's primarily wood ash from hardwoods such as oak, konara oak, kashi oak, zelkova, and cherry. No fire starters are used; instead, I use cedar leaves and kindling from coniferous trees. It has been sifted through a 1-2mm sieve and is in powder form. (Please note that fine charcoal may be mixed in.) It fits perfectly in a Takkyubin Compact box, and the content weight is approximately 1 kg. If you need more than 1 kg, please feel free to comment. It can be widely used for ash removal, cleaning, irori (sunken hearth), hibachi (brazier), etc. Thank you for your consideration.
