Has anyone everheard of Ajusa gaskets?

I recently purchased a gasket set off ebay and was wondering if these are really that good.

The seller claims that Ajusa is a OEM gasket manufacturer, but the head gasket is definity of a different material than the one I took out of my engine.

well i am an Europian costumer and driving a black top 110 kw primera GT p11 1998 model. once i blow my head gasket and sawthat the OEM one was Victor Reinz ( a german brand i think) . I go to a Nissan dealer and bougt a new one. Also that was Victor Reinz brand.Maybe Nissan sold out SR20 s with diffrent brand gaskets for diffrent markets.
