A 100% tin tumbler that fits comfortably in your hand. I made it easier to hold by making a dent on the thumb part. Since ancient times, tin has been used for sake cups and tea utensils, as it is said that "water in a tin vessel does not rot" and "it removes the unpleasant taste of sake and makes it more delicious." In addition, it has an antibacterial effect and can be used safely as tableware. The mouth is wide, so it is also recommended for water splitting and locks. Because of its high thermal conductivity, the bowl itself cools down well, and you can enjoy the change in taste as the ice melts over time. The soft touch of tin will gradually become familiar with your hands as you use it, and your own tumbler will be completed. Comes in a paulownia box recommended as a gift.

[Precautions for use]

• After use, use a soft sponge and wash with kitchen detergent (neutral). When the luster becomes dull, please use baking soda. Also, since tin (100%) is soft, do not rub it with a hard scrubbing brush. It may scratch the surface.

• Do not place near fire as it has a low melting point. Because it is metal, it cannot be used in a microwave oven. Do not use the dishwasher or dryer as it can get hot.

• Do not put in the freezer, as the tin may deteriorate due to low temperatures. Also, please refrain from long-term storage in the refrigerator. Also, do not leave sour or dark colored items in for a long time. Doing so may cause discoloration.
