This sounds stupid, but I work for a company that produces a few product ranges and sells them in different online settings. The product with branding do far, far better. Speaking also as a consumer, when I see a new product for sale that has no branding, I automatically assume it's being sold by a flash-in-the-pan drop shipper trying to make a buck off a product they did not manufacture, which tells me to avoid it.

Since there are a variety of free tools out there to create a simple logo, I'd say at least put that effort in before considering selling. Branding is part of the process flow.
