Perfect for sensitive gums, receding gumlines, and anyone who prefers a gentler brushing experience. | PURE HORSE HAIR BRISTLES: Ethically sourced and hand-woven into a real bamboo base. A gentle, natural clean with nothing synthetic touching your mouth. | NYLON FREE, GLUE FREE: Zero nylon bristles and zero synthetic adhesives. Bristles are hand-woven into the bamboo base, free from BPA, phthalates and PFAS. | 4 PACK, UP TO A YEAR OF BRUSHING: Swap your head every 1-3 months for optimal hygiene, so one pack covers up to a full year.
