Pure Copper Bird Bath Purification Disks

Three circular bird bath purification disks made of 99.9% pure copper. These assist in keeping water clear. Each disk is approximately 4” across. Can be used for pet water bowls as well. I’ve used them for a small pool so there is some scratches but nothing big. Asking $5 each Cash Cash upon meeting at Orchards Shoppers Drug Mart - 2526 66th Street SW
