100% Natural Bamboo Wood Bamboo "splits" are thin pieces of wood used as the core of masala-style incense sticks. These are NOT "incense blanks" (which are coated with wood powder) and aren't for incense dipping. These splits are thin, round, and smooth. They are a very consistent size, which makes it easy to produce a lot of sticks quickly. Each split is about 9 inches long, 1.3 mm in diameter, and round. These are perfect for rolling your own masala-style incense sticks.
