400ml is a proper mug — a full coffee or a generous dawa, not a polite cup. These are heat-resistant borosilicate glass, which is what makes them microwave safe: you can reheat a cooling coffee in the same vessel rather than transferring it, and they are dishwasher safe too, so there is no special handling. The small bulbous shape is deliberate, sitting comfortably in the hand where a straight-sided glass does not. Clear glass shows the drink, which is genuinely part of the pleasure with matcha, dawa, layered coffees and herbal teas. Lightweight enough for everyday use and clear enough to look good on a tray when guests arrive.

Buying guide
Borosilicate handles heat well but not shock — avoid pouring boiling water into a mug taken straight from the fridge, and do not set a hot mug on a cold wet surface. Because single-wall glass conducts heat, a full mug of very hot liquid will be hot to hold; fill slightly less than full or use the handle area. Wash promptly after coffee to prevent staining over time, and remove any cloudiness with warm water and lemon rather than abrasive scrubbing, which scratches glass permanently and makes it look worse.
How it compares
Against a double-walled mug, single-wall glass is cheaper and microwave safe, but conducts more heat to your hand and loses temperature faster. Against ceramic, glass shows the drink and reheats cleanly. For carrying coffee out, use a flask.
