WIDE BINDING CANE 4MM: Our smallest binder cane. This natural glossy bark cane, with a rise on top, is the strongest and best wearing material for chair seats. It is also similar to natural chair cane but wider and thicker. Highly recommended for porch rockers and outdoor chairs as well as the wrapping of joints on rattan/wicker furniture. Available in 5 sizes and packed in 500ft hanks. 1 coil will do an average 16″ X 16″ seat.
