Our bubinga wood cane holder can be used on any horizontal surface, either smooth or rough. The bubinga wood finish is such that gives the holder a wave like look and very bright when illuminated with light. The shiny surface makes it easy to be seen when in a dark environment with traces of little light penetration. The screw end of the clamp is adjustable to fit into any cane collar, even with the presence of collar covering, it still holds on tightly. You will never have to worry about your cane falling over and taking damage again.
