Kaikado Kaikado has been making high quality tea caddies by hand in their Kyoto studio since 1875, using the same 130-step process and even the same die-molds, but the "sentoku color" (copper) canisters and matching tea set are brand new. The air-tight containers are perfect for keeping fine teas safe from moisture and humidity, but can be used for storing just about any thing-think fancy desk accessories. We love how the gold, silver and copper lids can be interchanged for a unique, mixed-metals arrangement.
