Abstract: A tag for labeling an object includes a body and an elastic band formed integrally with the body. The body includes two main opposing outer surfaces and a peripheral surface therebetween, and the band extends substantially from one side of the peripheral surface of the body to form a closed loop. The body and the band can be made from silicone, and are configured such that the band can be wrapped around an appendage of the object to allow the body to be inserted through the loop, thereby forming a knot that secures the tag onto the object. The knot can be untied by loosening the band and pulling the body back out through the loop. A method of manufacturing the tag, as well as methods of using the tag, is also disclosed.
