These are about the size of a golf ball and all seem to work well. They're made of durable plastic. They are very colorful with the colors of blue, purple, green, and hot pink. These are NOT whistles as much as they are more like kazoos. No whistle, just the hum of a kazoo.You have to use alot of breath to get them to make the sound so it might be harder for smaller children to use.

We got these to hand out for Halloween and they will work but they are not very loud. My boys love them even though they said they have to blow on them real hard to get them to sound at all. I am sure they will still be a big hit.
