Resin
The resin provides a softer contact that encourages relaxation. They remain at room temperature and offer a soft but less tender and thick contact than a rubber bit
Caution: Resin bits are particularly vulnerable, it is strongly advised not to use a bit that is too damaged, as this could injure the horse's bars, tongue and palate.
