This notebook is almost a "Secretly Sonic" or a "Subtle Sonic" item. That's because it doesn't have an actual picture of Sonic (or anything else) anywhere on it. Its hard-card black cover just has a simple gray and dark gray font/s that spell out "Speed Freak" over and over again, in fairly small letters. It spells it bold, larger, very small, & also in Japanese letters. These letters appear to phonetically attempt it, because they don't match up 100% (which is pretty typical)
It is a Sega Shop online store exclusive, and is 15 dollars like the rest of their notebooks of this spiral wire type. This is a 2020 spring/summer item.
