These are great for the price, though I’ve never had any desire or need to use the smallest one. They smell strongly of BBQ at first, but from what I’ve read that’s a natural result of a heat treatment used to increase it’s durability and dark color (the heat cooks the sugars in the bamboo which creates the scent). Anyways, I’ve had them for awhile now and the scent is long gone.
