History

A history of the El Marko™ brand and what's next for the brand itself.

C.H. Hanson's metal tags are built to last. Their resistance to corrosion, fading, and general wear-and-tear makes them a reliable choice for long-term use. This durability translates to cost savings in the long run, as replacements are seldom needed.
