Tatsuaki Imai This pair of guinomi (sake cup) features the "Rikka (Six petals)" motif, which compares hexagonal snowflakes to flowers. Tin is a rust-resistant and tarnish-resistant metal, and its luster will last for a long time if you take care of it. Tinware is said to absorb impurities from water and alcohol, thus mellowing them out by eliminating the off-flavors. Tinware has high thermal conductivity, so you can enjoy a cool and tasty cold sake by putting it in the refrigerator for a little while. This pair set is ideal as wedding gift or anniversary gift.
