Found an eBay listing for one of his other cups: "This is an extra Klingon bloodwine cup, one of the smaller of the couple of different sizes seen on TNG and DS9 (for short Klingons who can't tolerate too much alcohol?). Finished off in a gray hammertone enamel, it's probably not recommended for actual drinking, but would make a dandy pen and pencil holder. Approximately 4" tall. Collection of Star Trek TNG Senior Illustrator Rick Sternbach."
