Black bamboo has culms that are green when they first emerge from the ground, and within months they acquire the natural black color with dark-brown patches that gives this bamboo a beautiful, rich, appearance. The culms of this bamboo are used extensively in Japanese woodworking and are excellent for indoor and outdoor decoration. Our Timor black timber bamboo poles come in an average of 3-4 inches in diameter. This means that each pole WILL vary in diameter between 3 and 4 inches. Due to the natural material, each END of the pole will have a different diameter because of the way Bamboo grows. They are made up of a thick wall of heavy bamboo and are crack resistant. One pole per package. Each Pole has small holes drilled throughout the length of the pole, for fumigation purposes. Color and appearance will vary due to the natural material. We CANNOT guarantee a specific size, only that the pole will be between 3-4 inches in diameter.
