My son always seemed to be reaching for my keys or any metal object to chew on. When I searched for metal teethers, I came across Yummikeys. Opting for the toy tether initially, which featured a metal ring and was reasonably priced, proved to be a great choice. Within a week of receiving it, my son was enamored with it. Subsequently, I bought the Teething Rings, which he adores even more due to the jingling sound they make. Each time we've ordered from them, the items arrived promptly within a couple of days. I wholeheartedly recommend Yummikeys!
