They look like jamex/v-maxx coilovers to me. Should be able to find em easy enough on ebay from other sellers with better info on what you're actually buying, pretty common on there. Never seen em quite that cheap though, usually if something seems too good to be true, it usually is!
A friend of mine had vmaxx on his 1.9tdi avant, seemed pretty good for budget coilovers, if all you want is height adjustment bit still keep a fair bit of comfort.
