Which german websites can I use to sell perfumes from my collection?

I bought a numerous samples from Woodberg and they sprinkled my package with a perfume which I loved that fast that the same day I've ordered a full volume perfume.
Unfortunately, after receiving it today I understood that it smells very differently on my skin and I didn't like it at all.
I can't return the item since I've opened the package already (but haven't used it as I got a sample of it too).

I was thinking about Kleinanzeigen, but due to some reasons it's prohibited to trade perfumes in there.

Also I've used Ebay but I'm afraid I'll have to wait for quite a while till the buyer will appear.

Is there any recommendations?
