I love this type of charcoal as it burns so cleanly, without smoke or odor. It’s also free of chemicals or additives. I was so happy to find a dependable source for it as it became hard to get here in NYC. I’m looking forward to trying more items from Sphere + Sundry.

Burns so clean, no weird smell, and stays lit forever. I hope S+ never takes these out of stock because I never want to go back to other kinds of coal again!

This charcoal is so much cleaner burning than the widely available incense briquettes. While there is definitely a charcoal odor it is not carry the acrid, chemical malodor of the round briquettes. I appreciate the much smaller size as well.

This stuff is the best: easy to ignite and clean burning. Seriously, I didn't even realize how clean a charcoal brick burn could be until I started using this stuff. I am now a charcoal snob; the cheapo self-igniting charcoal rounds I used to get from the Bad Man's Digital Shopping Platform smell super strong to me now.

I like to put a little mica sheet on top of one of these and put the incense on that.

Also! Heather (who left the review below), on the off chance you see this: rotate the lid a quarter turn! I had issues putting the lid back on mine too until I realized the box is slightly rectangular, not square; the lid only fits going the one direction.

This product is wonderful, I’ve used it many times. With this particular package, however, the lid didn’t fit properly on the box.

I appreciate the smaller size of this charcoal. It comes in a beautiful box with Japanese lettering on it. I start using it while still red hot ( not cooled) with no problems. I’m using a ceramic cup filled with pink sea salt.

Easy to light. Clean burning with no smell.

Very easy to light - a low candle flame is sufficient - and very clean burning. It is the highest quality charcoal I have used. It lasts 20-30 minutes.
