The 14” Mega Ring is constructed of seven layers of material. There are three Layers of industrial grade luggage material, three layers of PVC and finally one layer of soft fleece. All seven layers are rolled together and then sewn together in a one inch cross pattern to prevent layer separation. Each toy's seven layers of material are sewn together with two rows of linear stitching and two rows of cross stitching. Those four rows of stitching are protected with a black trim that is sewn three more times! Additional industrial grade luggage material webbing is sewn around the outside edge with three rows of stitching to cover and protect the first four rows of stitching. Every Mega Ring squeaker is safe and quiet because they are sewn into a safety pocket beneath seven other layers of materials. Each Mega ring is washable (air dry) and it floats. The Mega Ring series is designed to be play toys and not chew toys.
