Molloss

Okay totally worth viewing for the introductory flash if nothing else, one part shakey-cam one part disturbing music video background, sadly this means its deep linking and accessibility fail as far as I can tell.  The collars themselves also appear to justify the atmosphere on the site, looking robust and beautifully industrial.

Okay so this is a serious collar site for serious leather buckling collars, it has serious all over it.  They've got a nice range of good looking and really interestingly designed collars.  Some with two layered or serious etching and just an awesome selection of really chunky and beautiful hardware to put on the collars.  Construction looks robust, but these things are not subtle, if you were wearing one there would be no mistaking it was an awesome chunk of neck hugging leather :)
