A 6 Inch Tall (15 cm) Dodecahedron Planter.
This wonderful planter is 6 inches tall and 7 inches (18 cm) at its widest point.
The pentagonal opening will allow a 4.25 inch (10.8 cm) diameter circle to pass through it. This means you can place a 4 inch pot directly into this planter for a quick geometric look.
As your plant grows, you can plant it directly into this planter with plenty of room for root growth.
