Tea Forté
Specs partially disclosed teaforte.com ↗
Tea Forté's signature pyramid is, by the brand's own description, a food-grade PET "silken" mesh - petroleum plastic, the same polymer family as plastic bottles. It's the premium, design-led version of exactly the format the microplastics research measured: a plastic pyramid steeped in near-boiling water. The presentation is beautiful; the material is plastic.
How clear are their specs?
Describes the pyramid as "silken" and food-grade PET in its own tea-notes content, but the plastic nature isn't surfaced in the main marketing - a buyer would have to dig to learn the infuser is PET.
