This set of musical bells by #Koogel is totally amazing. Tge sound is terrific on each bell. I love the wooden handles that are easy to grip. The bell part themselves are made of metal so a baby can easily break something by throwing them or hurt themself by hitting another baby or small child with the bell. Six months is way too y oi ing for this set of bells. A much more appropriate age would be 3 years and up when a child can comprehend the consequences of tossing this item and hitting another object and breaking it , or hurting another person. That said I did not remove any stars as the quality on these bells is superb and will create hours of fun for kids ages 3 years to adult as even adults have been known to play the bells. This is a great introduction into a musical instrument. At $23.99 you really can't go wrong!
