These are a smaller version of the Laguna PT796 injection molded pond basin. They are Laguna PT788 42x28.5x12 60 gallon basin. Found this stack of 8 on Portland's Craig's list and the seller was motivated enough to deliver them to Eugene. A nearly 4 hour round trip I was not up for making in this 95 F degree weather.
Here is the Laguna Tag.
Ideal for deck ponds or raising Ranchu!
