From Inkipedia, the Splatoon wiki
Rockenberg (Japanese: ロッケンベルグ Rokkenberugu) is a brand within Splatoon. Rockenberg items have a 5x chance to roll Run Speed Up, while a significantly reduced chance to roll Swim Speed Up. The logo appears to be an 'I' with a eel constricting around it, forming an upside-down and flipped 'R'. It has some text at the bottom written in Inkling.
