High-density food-safe ceramic fired under high heat creates seamless glossy glaze, oil-proof, stain-resistant and wear-resistant for long-term daily use. Integrated curled rim restores nostalgic enamel cup retro texture, no risk of metal enamel rusting or edge peeling. Small 220ml portable size fits narrow office desktops and mini car cup holders well; chunky curved handle effectively blocks heat to prevent scalding when sipping hot espresso, black tea and warm milk. Smooth monochrome exterior is suitable for brand logos, text customisation for wholesale clients.
