Worth the money!

I was blown away by the quality of these planters. They far exceeded my expectations. I bought them to go on either side of the front door and they definitely class up the door and front porch area. The walls are thick and sturdy and have a handy built in watering system if you choose to use it. The details on the sides really stand out . They look like they will last for a good long time as well.
