More Suehiro "Rika" Stones
The Suehiro professional line is commonly (and incorrectly) referred to as Rika series in the English world. We have chosen to use their correct names in Burrfection Store. The name Rika is in fact the name of the #5000 grit stone in the Suehiro Professional line. If you are looking for a Rika 3K for example, you are actually looking for "Ouka" #3000, which is in the same professional line as Rika 5K.
