About the backrooms
If you know, you know: the mono-yellow wallpaper, the buzz of fluorescent lights that never turn off, the carpet that's somehow always damp. The Backrooms collection turns internet horror's favorite liminal space into wearable deadpan — a paint swatch for "Backrooms Yellow No. 1998," a one-way boarding pass on Liminal Airlines, a five-star review from a visitor who never left, and an OSHA sign warning of no-clip hazards.
Every design is original and printed on demand in the USA on a soft heavyweight tee, shipping in 2–5 business days. They're the perfect gift for the analog-horror fan, the r/backrooms lurker, the liminal-space photographer — or anyone who's ever looked at an empty office hallway and felt watched.
From Level 0 to the Poolrooms, these shirts hum at exactly one frequency: forever. Welcome back. You were always here.
