Can I request a specific cover, label, or graphic style for my GBbook?

In many cases, yes, especially when the product already includes customization options or when the request fits the visual language of the project. A GBbook is not only a functional cartridge. It is also a designed physical object, so label, presentation, packaging, and overall aesthetic coherence matter. At the same time, not every request will make sense as-is. Some ideas may fit well within the tone and structure of the product, while others may need adjustment for practical, visual, or production reasons. So this is exactly the kind of customization that is often possible, but best discussed clearly if the request goes beyond the default options.
