Here is a factory sealed copy of Sonic Adventure for Dreamcast. It’s been stored indoors in a box and in a smoke-free environment. What sometimes appear to be white "crayon-like" lines in some photos are actually reflections from my phone - not marks or smudges. (You'll notice that they'll be in some photos, and then not in others - this is due to the different angles I was photographing from.) Feel free to ask any questions. Insurance will be added to shipping cost.
