This stackable plant tower is a multipurpose desk accessory for the modern minimalist. Each triangle can stand alone by itself, or can be stacked together to form a tall tower or a modern structure. The tops of these triangles work as an air plant holder, & can also lock into the bottom of another triangle. The bottom of the triangle provides a dish for you to place paperclips, pushpins, or other small desk accessories. You can even use these as pen holders! Available in black, white, silver, or red. Each triangle measures 4.5 W x 3.9 L x 3.7 H (114mm W x 100mm L x 95mm H) & is 3D printed with a biodegradable, plant-based plastic. If you would like a different size or color, request a custom order! We 3D print our products ourselves, & can customize any of our products. Want to add an air plant?
