This is a set of three Edo-period cut glass cups. Perfect for drinking cold sake on a hot summer's day. While this type of glass (cut glass) is often sold as Edo cut glass or Edo glass, including embossed and British-made items, this particular shape is not found in Britain, and the craftsmanship is undoubtedly Edo glass. While there is some chipping on the rim, a complete set of three cups is extremely rare. The coins are for size comparison purposes and are not for sale.
