Good Morning from Sunny Hawaii.
I live on OAHU, so, I don't know the dealers in Hawaii (Big Island)..
Sorry I'm useless..
Just to let you know, there are different kinds of KOA.. Each Island has it's own.
I forgot who's was the dark ones and who had the light color ones.
Many KOA Woodbox guys don't want to sell their stock.
One owner told me it's hard to find and the price will go up because of that rarety.
I think, once yo arrive, just ask anybody. The island people would know who's selling KOA.
Good Luck and a safe visit!!
Aloha,
Alton
