T-shirts.

T-shirts for testers finding bugs developers swear are impossible. About edge cases, reproduction steps, and the satisfaction of proving that yes, it does break. For QA engineers who've learned that "it works on my machine" means nothing. Designs about the gap between test coverage and production reality, between happy path testing and what users actually do. Made for testers who know their job is being creatively destructive and developers who've learned to appreciate them.
