Thank you for viewing this item. "Cactus Bone" How about using it as part of your interior decor? * Length: Approximately 16cm * Diameter: Approximately 7cm The inside is hollow and there are many holes on the sides, but it has a slight weight to it. Originating from Mexico, its unique shape is distinctive, very stylish, and lovely. It's also popular as a mounting material for air plants (Tillandsia) and for terrarium layouts. It can also be used for displaying plants or as a hiding place for insects and reptiles. Thank you for your consideration.
