Toothbrush is toddler size only
Color: Pink
This toothbrush is more for toddlers and not for school age children. The water flosser portion can be for older children

Super Cute, Fun, & Effective
Color: Lightgreen
This set of water flosser and electric toothbrush are just adorable! The shapes of them fit in the hands really comfortably, but also add to the cuteness as the shapes of the animals! Yes, this is meant for kids - so the toothbrush heads are small (for little kids), and the water flosser doesn't spray terribly hard. BUT they're still very effective. I especially like the water flosser. It can be taken into the bathtub/shower while bathing, so the spray doesn't end up going places we don't want water to go. It has a small tank of water, and I recommend using room temp water (rather than cold) so that it's comfortable on the gums and teeth. Also to note, the flosser doesn't work when it's sideways or upside-down - it needs to be held upright. This set is so cute, easy to use, easy to re-charge, and very comfortable. It's also very good quality - a great purchase. I love it!
