What are some advantages for fiberglass planter verses concrete or ceramic planters?

Fiberglass planters can be up to 10 times lighter than concrete and terra cotta planters. It would only take one or two people to move virtually all of our fiberglass planters.
Concrete planters have the potential to break or chip when dropped or miss handled. Fiberglass won’t break from minor miss handling and the finish may chip, but can easily be repaired with no damage occurring to the actual planter structure.
The fiberglass molding process makes our planters water tight by design. We can also incorporate drain holes to allow liquid to drain when used outdoors.
