Description

When your boss battle skills meet The Office mug. This tee crowns Bowser as the ultimate “World’s Best Boss,” blending gaming culture with workplace comedy. Perfect for gamers, coworkers, or anyone who loves a clever crossover. Offered in comfortable mens and womens sizes for everyday wear.

Fit & Features

  • The tee you’ll reach for every day — soft, breathable, and built for lasting comfort. Made from soft-style midweight fabric with a modern classic fit, and has a soft finish you’ll love to wear. After printing, each item is cured under high heat to prevent fading and flaking.
  • Material:
  • Black: 100% Ringspun Cotton
  • Sport Grey: 90% Ringspun Cotton / 10% Polyester
  • Care: Machine wash warm, tumble dry
  • Fit: Predominantly true to size. If in between sizes, we recommend going up one size as garments shrink 1–2%.
