# In Use | No. 547, Unisex Long Sleeve T-Shirt

The scratched and aged texture of brushed metal hardware is captured through meticulous cross-hatch ink work in this rendering of a sliding lock. Breaking the monochrome mechanics is a bold red indicator block, featuring crisp white lettering and Japanese characters that signal an occupied room. Displayed on a long sleeve t-shirt, the stark contrast between the gritty metal and flat red shapes commands the eye.  
  
A simple everyday mechanism becomes a study in personal boundaries and the quiet necessity of closed doors. It is a universal artifact of claiming space, even just for a moment.
