The distinctive, net-like hollow shape is a fascinating form created when a cactus naturally dries and becomes woody. The black spots are ash, etc., that entered the skin's fibers when the cactus flesh was burned. The slight white coating on the surface is also not mold, but ash, similar to how the surface of charcoal turns white. ◾️Size Length: Approximately 15cm Diameter: 3.2 - 3.5cm ※Please note that there may be individual differences in size and shape due to the natural materials.
