Knolling photograph, shot perfectly straight down: a complete Korean calligraphy set, the four treasures of the scholar's study, laid out on a pale hanji paper mat in strict grid alignment — four brushes in a row sorted by size with their bamboo handles parallel, an inkstick lying straight, a dark stone inkstone with a shallow well of ink, a small white porcelain water dropper, a stack of blank hanji sheets squared off, a brush rest, a felt pad, two wooden paperweights laid parallel, and a red seal stone whose carved face shows only a simple plum-blossom pattern. Even shadowless light. No text, no letters, no characters, all paper blank.
