Set of Two Chinese Scroll/Calligraphy Stone Weights

Description

Set of Two Chinese Scroll (or calligraphy) Stone Paperweights grey-green in color with Chinese Kanji characters painted on both. The two large Kanji characters are split between the two stones. I have been told by a friend the Kanji says “work and study hard”. [If anyone knows, I would appreciate the assist!].
The stones have a clear protective coating for protection, which gives them a glossy sheen. Each stone is rectangular in shape and measures 7.5 inches by 1.25 inches by 7/16 inches. The type of stone is unknown.
These are being sold “as is” with no return so please look carefully at the photos. I am happy to take additional photos upon request and respond to any inquiries for more information.
