Japanese Charcoal (Oga Sumi) 22lb Oga sumi is a traditional high quality charcoal 22LB(10KG) made by burning wood in the absence of oxygen. Our moderncarbonizationprocess produces strong and high density charcoal. Its unique hexagonal shape provides efficient storage, wide surface area, and easy stacking of charcoal during usage. The round hole that runs through the middle ensures air inflow for efficient burning. By using tropical hardwood sawdust as our material, it can burn longer and hotter with high calorific value and unique properties of hardwood. The complete carbonization process also makes the charcoal smokeless and consistent.

We believe your food deserves only pure aroma from the charcoal, and nothing else. This ogasumi is use same japanese technique and Quality .made in indonesha Please restaurants for order inquiry
