- NATSUME is not so airtight like our steel canister in which Matcha Super Premium and Premium are packaged. So, when you store Matcha in NATSUME, please use up within a few days.
- If you feel uncomfortable with the smell of new lacquer ware before use, leave it in an airy room for a few days. The lacquer smell will vanish.
- Never soak lacquer ware in water.
- Never leave lacquer ware in direct sunlight or high humidity, to avoid the risk of transformation, discoloration and mold.
- If you find an oily spot or fingerprint on your product, wipe with a soft cloth or paper carefully.
- Never use scrubbing brushes, scouring powders, or a dish washing machine.
