I'm imagining a teacup - made of china, decorated in some way, capable of holding a few mouthfulls of ~75C thin liquid, smaller than a big mug, larger than a shot glass, with a handle sizes for the tip of one finger, delicate, ceremonial; concept space constrained to broadly teacup-ish area. But not a specific teacup unless it becomes important whether it's a plainer heavy duty cafe teacup or a grandma's Royal Jubilee promotional teacup.
