Longmire has a website that pretty much covers the map. http://www.cufflink.co.uk/
Personally, I think that they are arrogant and offensive twits. Â And much of their stuff can be found at other jewelers. Â Before the reorganization, Asprey also had a good selection and did some nice custom work for me. Â But Longmire has a very good product line. In the less expensive end, shops like Benson & Clegg do quite a lot, as do other Savile Row firms.
