Released back in 2005, these cufflinks (in a few different styles) were released by Mag Mouch.
 
These have been in storage for 20 years now, and as such the metal display box the cufflinks are presented in has begun to corrode. The cufflinks are still sealed inside though and appear to be as new. The packaging is complete with the branded Doctor Who slip cover. The price has been reduced to reflect this.
