February is Valentine's Day, the season for expressing your feelings to your special partner. At Studio Smith Sapporo, we have prepared a special limited-time plan with great value, hoping that you will give the gift of "time spent making a ring together" rather than simply buying a ring. Along with luxurious chocolates that add color to Sapporo's winter, we will help you create a one-of-a-kind ring.
