Hardwood charcoal, often referred to as lump charcoal, is a premium fuel source celebrated by grilling enthusiasts and professional chefs. Unlike briquettes, it is made directly from pieces of dense, natural hardwood like oak, hickory, or mesquite.
"The size for coconut shell briquettes and hardwood briquettes is 3×3 cm. The size for charcoal depends on the order; some are 10 cm long with a 4 cm diameter, and others are already broken down into 2×2 cm pieces."
