Flash Riot
by Emily Carroll
Tattoo Flash. Loud Graphics. Everyday Rebellion.
Not every masterpiece hangs in a gallery.
Some end up on leather jackets, skate decks, tattoo walls... and now, your favourite pair of Knobbys.
Flash Riot is a collision of old-school tattoo culture, punk attitude and playful illustration. Designed in collaboration with illustrator and designer Sophia Ren of Renographics, this collection packs every inch with symbols, stories and a healthy dose of organised chaos.
Wear Your Story
Tattoo flash has always been about self-expression.
Originally displayed on the walls of tattoo studios, "flash" refers to pre-drawn designs ready to become part of someone's story. Skulls. Roses. Snakes. Daggers. Lucky charms. Every icon carries meaning, whether deeply personal or simply because it looked cool.
Flash Riot takes that tradition and remixes it with Knobby's signature sense of fun.
Flaming skulls, hungry sharks, lucky stars, hotdogs, roses, moons, chains and snakes collide in a riot of colour and attitude. It's loud. It's playful. It's a little bit rebellious.
Exactly how we like it.

Just organised chaos
