Fully adjustable between 15 and 30 inches, this is a great belt that can grow with your child. The adjuster slide is polished nickel and matches the buckle. The buckle is unique in how easy it is to use and with no snaps, prongs, or magnets that can grab little fingers. Simply push the solid end through the open end, twist and pull for a secure fit. The elastic stretch allows for a comfortable wear that allows for easy movement.
