Thank you for viewing! These retro and adorable arm rings are for children. They have two air chambers for stable buoyancy, and are designed to be safe even if one chamber deflates! They are also designed to stay on the body and allow children to play safely in the water. Unlike regular swim rings, they don't require holding on, so children won't get tired easily, making them perfect for getting used to the water. *This product is a toy, not a life-saving device.
