Secret Tunnel Club

$22.31 SGD

For those who know there’s always another level underneath the city.

This design keeps it simple and suspicious: bold yellow text on a black shirt reading SECRET TUNNEL CLUB part weird-news reference, part underground society joke, part “don’t ask too many questions” energy. No giant graphic, no explanation, just the kind of phrase that makes people squint at your shirt and wonder whether they missed a documentary.

Perfect for fans of urban legends, sewer lore, bad infrastructure, forbidden corridors, and uncomfortable follow-up questions....and what was with that mattress?

Wear at your own risk.
