What the rule is
Plastic does not belong here.
No plastic in contact with the body. We accept materials that are inert and free of documented health concerns in body contact. We reject plastic, alongside a named list of ingredients with documented health concerns: parabens, phthalates, synthetic fragrance, BPA, BPS, PVA, among others.
Specific materials in any product are disclosed on its details page. The full accepted and rejected list is published in how we evaluate, and it updates as we encounter new materials.
A product either meets this or it does not.
