Primals
Primals positions its toothbrush as a natural-bristle alternative: a bamboo handle with boar-hair bristles rather than nylon. As with any boar-bristle brush, confirming the bristles are 100% boar (and not a boar/nylon blend) is worth doing before buying.
How clear are their specs?
Markets the bristles as boar hair on a bamboo handle, but published material-composition detail is limited compared with the more explicit nylon-free brands.
