SPECTRUM M-1 is the first joint from the Grog® Prototype Unit™, built exclusively for SPECTRUM—a pro-grade, pump-action marker built like serious equipment. Metal body, laser-etched branding, and a 7 mm chisel tip that stays razor-sharp long after standard nibs tap out: this is the industrial-strength output that writers are after. This tagging machine is loaded with Grog’s signature Mercury Chrome Paint™—velvet flow, mirror-bright chrome, highly opaque—driven by a tight pump system for controlled flow. It’s issued only in a test-size run and sealed in a chromed pouch. The SPECTRUM M-1 is ruthless in the hand. Your beloved PX-30 can now take a rest.
