The jumbo one-ply toilet paper offers 2 1/2 times more paper than a standard roll. The U.S. Environmental Protection Agency-compliant product is made of 100 percent recycled fiber, and a biodegradable core makes it earth-friendly. It comes 2,500 sheets per roll and 24 rolls per case. 800-292-1305; www.polyjohn.com.
