In fall 2020, the Sega Shop released a selection of 'graffiti inspired' Sonic items. This spiral notebook with hard-card cover is one of them. It's about 16 dollars which is pretty pricey for a normal notebook who's only Sonic feature is the cardboard/thick cover.
The design here is 'ripped paper designs', as each section appears to be art that is torn-through to reveal other things. You've got Sonic faces, Eggman, slogans you can't read, annoyed-Sonic face, and a Sonic's-glove peace-sign there at the bottom which is unaffected by the effects on purpose, making it look like a sticker. The whole thing uses only blue/white/gray/black for the colors, which makes Knuckles and also Eggman blue where they appear.
The effect is to be busy, but it does stand out among other designs. There has not been a notebook with this type of 'montage' or maybe 'collage' type of theme before. It's interesting, but not sure if 16 dollars worth of interesting.
