This wooden baby rattle is the perfect size for any child. The rounded edges make the rattle easy to hold on to and is very comfortable in your baby's hand. The rattle is sanded to a satin smooth finish. The one handed grip is great for babies still learning how to hold on to things. The two handles will allow an easier grip for your baby. The wooden baby rattle measures 3.5" around and 3/4" thick. The steel ball on the inside makes the rattle sound. It is secured and will never come out unless the toy is broken.
