The classic parody dojo tee gets an upgrade. The Duck’s Ninjitsu Circle Crest Tee brings back Master Duck in a bold new design — but remember, only real ninjas know.

By popular demand, the legend returns. The Duck’s Ninjitsu Circle Crest Tee is the updated version of the parody dojo shirt you’ve seen in Goldenbell Training videos — redesigned with a sleek circle crest layout and bold red background.

This shirt is for the initiated. Those who know the ways of Duck’s Ninjitsu don’t need to explain it — and those who don’t will never understand. Featuring Master Duck in full ninja stance, this design captures the perfect balance of martial arts humor and secret dojo pride.

Printed on the Gildan 6400 Softstyle Tee, it’s lightweight, soft, and durable enough for shadow missions, sparring sessions, or just everyday laughs.

  • Design: Master Duck circle crest with “Only Real Ninjas Know” text

  • Fit: Classic unisex, soft & comfortable

  • Fabric: Gildan 6400 Softstyle cotton blend

  • Best for: Martial arts fans, parody lovers, and ninjas who know

🥷🦆 The circle is complete. The duck abides.
