The Steep Mug — Borosilicate Glass Tea Mug with Stainless Infuser & Lid

One mug, whole ritual. The Steep Mug is the complete single-cup setup: borosilicate glass body, deep 304 stainless infuser, and a steel lid that holds the heat in while your leaves open up.

Glass and steel, nothing else. The body and handle are one piece of borosilicate; the infuser and lid are solid 304 stainless. No plastic frame, no coated mesh — the construction the rest of our shop is built on.

The lid works twice. Cap the mug while steeping to trap heat and aroma, then flip it into a rest for the dripping infuser when your tea is ready.

A real basket, not a tea ball. The infuser runs nearly the full depth of the mug, so whole leaves actually unfurl — better extraction from the same leaves.

Honest capacity. 500ml (16.9 oz) filled to the brim; plan on a generous 14 oz cup with the infuser in place. Sized for a proper mug of tea, not a tasting cup.

Micro-perforated steel rinses clean under the tap — tap out the leaves and it's ready again. The one-vessel answer for desks, dorms, and anyone you're trying to convert to loose leaf.
