Is it weird to have a website where I sell a single product which has a different name from the domain?

I’m going to be selling a single product which I have a good name for. I plan to add more products later. The domain name I already have is relevant to the niche and is supposed to be my brand name. But is it weird to have a single product under a different domain name?

Edit: I’m doing print on demand, and I’m not sure there’s any way that I could incorporate the brand name into the packaging.
