Japanese natural whetstones Nakayama Suita Koppa NSK1
Most sought after finishing stones for razor users. No inclusion or line with light brown when dry and slightly darker brown (to be precise instead of red). Quite a hard stone so best to use with Nagura. Please note that partial of the stamped on the stone was removed but the stamped on the side is still intact and there is no number on the stone in which the box had. Came with a soft box.
