Oni

Summon the spirit of ancient tea masters. The handmade Tenmoku tea cup named Oni wields a iron glaze that erupts in dark crimson and black, with demon mask motifs etched into its surface. Crafted from high-fired porcelain, it showcases shimmering oil-spot crystals that catch every angle of light. This cup is for tea lovers who crave a bold, meditative daily tea ritual—its deep tones and fiery accents transform each sip into a moment of power. Whether for matcha or oolong, it’s also a meaningful gift for those who honor tradition. No two cups are alike, making your Oni a singular artifact of fire and clay.
