Coventry alloy urns are one of our most popular items. They are lightweight and virtually indestructible. The Coventry Cobalt Blue features a unique hand finish which is coated with maintenance free polyurethane. The Coventry Cobalt Blue design is at once uplifting and bright, while it is also dignified and comforting. We know that it will serve as an appropriate resting place for the remains of a loved one, and we thank you for considering an urn from UrnConcern. Simon, and the UrnConcern staff. Sizing Made Simple One pound of live weight equals one cubic inch of cremains. 3" = 3 cubic inches 6" = 42 cubic inches 7" = 87 cubic inches 10" = 202 cubic inches For example; A 175 pound person, would yield 175 cubic inches of cremains, which would fit into a 10" urn.
