"We make it easy to take great care of your little one’s teeth and gums with the new Grin Kids Dental Flossers!! The floss thread is made from a luxurious material that doesn’t tear or shred easily. The corn-starch handle is easy for little hands to use and helps reach those “hard to reach” spaces between teeth. The handles on our kids flossers have rounded ends to prevent little hands from hurting themselves. Directions for use: Floss before brushing your teeth. Regular flossing can start as soon as two teeth are in close contact Children should always be supervised by an adult while flossing.
