Good quality cube coals which last longer than normal coals.
Normally i use Starbuzz cocobuzz 2.0 coals since most stores don't carry titanium but these ARE A MUST!!!! Hands down the best coals I've ever used. No smell while lighting the coals like you get with CocaNara brand. Most important is how long the coals last! Easy 2 hour session on one set of coals. If anytime i need coals titanium cubes is the way to go!!! Plus i was skeptical ordering offline but my coals arrived on time in perfect condition!! NO PROBLEM AT ALL!!!
