This is an abbreviation for Silver Filled, indicating that the base material (such as brass) is covered with silver. Goshichikiri Kamon Silver Cups Unused, but due to long-term storage, the 6cm silver cup has some stains. Please check the photos. We are careful with packaging, but it will be delivered in simple packaging. There is no wooden box, so we plan to wrap it with cushioning material. Also, please understand that these are used items.
