Handmade in Kyoto by a 6th generation craftmaster, Takahiro Yagi, Kaikado canisters are known in Japanese as chazutsus and principally used for storing tea. However, KAIKADO canisters can also store a variety of non-tea items inside including coffee, seeds, beans - anything that must be kept away from moisture. Each canister is made entirely by hand with methods so precise that each canister lid will close on its own without unnecessary pushing or pressing. Simply line up the visible seams on the side of each canister and observe the lid descend on the canister's body all on its own. Slowly and gently, you'll be able to hear the faint sound of air gently expelling from the caddy so you know it's becoming airtight.
