For those who prefer to use the chasen, the traditional bamboo matcha whisk. \nDimensions: 2.5\" tall,  4\" diameter\nCapacity: 8oz. / 0.17L at full capacity, but we recommend 4-5 oz for matcha.\nCare: Microwave safe and dishwasher safe, but we recommend careful hand washing  to avoid chipping.  \nPLEASE NOTE: Because each piece is truly one of a kind, expect some variations in color and shape.\n*Ships only to US and Canada;","images":["https://cdn.shopify.com/s/files/1/0222/8459/9373/files/TUM-KOH-KUMO-01-tini.jpg?v=1748900404","https://cdn.shopify.com/s/files/1/0222/8459/9373/files/TUM-KOH-KUMO-02-tini.jpg?v=1748900404"],"price":69,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:44:26.511Z"},"share_url":"https://firestarter.network/l/lst_iZ1NtPrv","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
