Bought new X-E1 and display 18-55 lens - certificates?

Hi guys,

just bought a new X-E1 (black) and a 18-55 lens (was on display).

As the kit on display was a silver body (and the lens on display was the last 18-55 they had), I got 1.) an individually boxed black body and 2.) the 18-55 from the silver kit, without packaging, in bubblewrap.

I got a small discount.

I did not get any original packaging / documentation for the lens. The receipt clearly states both serial IDs for both body and lens.

Question: do I need any more documents, or am I fine? (from a warranty point of view)

Thanks a bunch in advance,
