Grog Squeezer 25 Street Killer Ink (SKI)

This is a marker that causes havoc! Its extraordinary Stronghair™ 25 tip scares the shit out of all other markers. Once you start writing on something, it won’t go easy on it: Street Killer Ink™ has a secret recipe (alcohol-based high staining dye ink) and its ink gets deep into any surface and dries out instantly. Even if they try to buff them, your tag’s ghost-stains will forever live on!
