CocoUs Big Cubes are built for longer sessions and bigger heat. Each 72-piece box delivers the same clean-burning, low-ash performance you expect, now in a 26x26x26 size for extended consistency and fewer coal changes. Made from 100% natural coconut husk, these coals produce no added taste and deliver high, steady heat perfect for both foil setups and HMD devices. For best results, use with an electric charcoal heater.
