@Snowfire is this something that can be found just about anywhere in the UK? I have friends in the south near Portsmouth and I'd really like to get my hands on a few.
Yeah, majority of shops will sell glasses like this. It's just finding the right ones as there are so many variants. The ones I bought and sent to shadeone, the website doesn't seem to exist anymore, but pretty sure you could find others. Your best bet, would be to find them online on a UK website, then get them to order that way.
Maybe hit Shadeone up to post some more pictures if still around of the base, as that's where the pattern/style seems to be different.
