Penguin Address labels feature these funny and unique birds that can't fly. These designs are available exclusively from Extra Value Checks. Their black and white coloring is great camouflage in the water, protecting them from natural predators such orcas, sharks, sea lions, and leopard seals. Unfortunately, their black tie attire does not protect them from human threats like oil spills, pollution, illegal poaching, and global warming. Penguin Address labels are self adhesive and matching checks are also available.
