サイズ・素材等 Material: brass Size: 19 x 19 x 180 (mm) Silver (nickel plated) お手入れ・取り扱いについて How to care: After use, do not use scrubbing brushes or abrasives, but wash in water and dry in the shade. Handling Precautions: A small amount of copper ions dissolve in water and prevent bacterial activity, so green rust (patina) may appear from the inside depending on the environment in which it is used, but it is not toxic and there is no problem in using it. If it rusts, wipe it off with a soft cloth.
