The 2.75mm-wide clear plastic strap is designed to provide superior esthetics, better tooth contact for excellent retention, and durability without scratching tooth enamel, restorations, or veneers. According to the manufacturer, the BPA-free, food-grade strap material is resistant to stains, virtually unbreakable, and can be adjusted with a three-prong plier.
