Vitrified food-grade ceramic undergoes high-temperature firing to form a compact, seamless glazed layer that resists stains, scratches and everyday abrasion. Random natural speckles deliver warm rustic countryside charm, avoiding rust and chipping troubles common with vintage enamelware. Its compact 260ml size saves desktop room and fits standard car cup holders effortlessly. The thickened curved handle insulates heat well, preventing scalds while enjoying hot coffee, tea or warm milk. The plain exterior allows custom logos, phrases and artwork via silkscreen printing to meet demands of cafes, enterprises and souvenir retailers.
