This pair of cufflinks belonged to my uncle who worked in California. I recently was given the cufflinks and to date have not been able to figure out what they represent. I have included a picture, but I'm not sure if it is upside down or not. Any help would be appreciated.
Nope, it's just five squares, which there's no character for in Chinese.
There is no character that I know of in Chinese but there is a similar character pin(3) 品 which means product or commodity.
