Pompompurin (ポムポムプリン) as a milk bottle, in glazed porcelain. Sanrio's copy frames it as merchandise for a Purin who dreams of getting bigger and bigger, which is roughly the energy of a 410 mL mug.

About 11 × 8.5 × 12 cm, holding 410 mL — larger than a standard mug, with the brown beret moulded in relief on the front and a matching brown handle.

Sold out on the Japanese store. Porcelain, so hand washing is the safer choice.
