Is it self-defense? Is it self-delusion? Who cares — it’s hilarious.

This 8.75” x 2.5” matte bumper sticker is the perfect way to warn tailgaters, nosy parkers, and highway hooligans that you’re technically a karate master… of reading about it. You’ve got a book. Probably chapter 3 by now. Maybe the glossary.

Whether you're a martial arts enthusiast, a proud couch warrior, or just someone who values their personal space and sarcasm, this sticker packs a punch (in theory).

Features:

• Matte finish — because shiny stickers are for show-offs.

• Weather-resistant — your book may not survive the rain, but this sticker will.

• Bold, black lettering that screams: “I’m dangerous… with literature.”

Stick it on your bumper, laptop, water bottle, or dojo (if your sensei has a sense of humor). Just be ready for people to bow in confusion.
