In other Saturn news, fansite Segatastic noticed that Enterbrain’s Sega Store has brought back its Saturn-shaped backpacks, over ten years after the company stopped production for the actual console. The nylon bag sells for a ridiculous $72 (¥7,140), and is only available in the less exciting and not-at-all rare color of gray

Ridiculous or not, gray or not, I still want one. At a size of 310mm by 320mm by 110mm it should hold quite a bit!
