Colors: black, blue, grey, terra cotta, or green. The barrels are made from heavy, food-grade polyethylene containers that have been recycled and may show minor wear. The barrels are BPA free. Barrels have a mesh screen on top to keep mosquitoes out, and there are two locations possible for the spigot - one as shown, and the other much nearer to the bottom of the barrel. Barrels can be connected in series using a hose (purchased separately) to dramatically increase the amount of rainwater saved.
