Key Ring with Radiator Key and Trolley Coin

The key ring covers two useful functions at once: A heating vent key and a reusable Trolley Coin are both embedded into the key ring.

The Trolley Coin holder is made of solid metal is designed like a screw nut. The surface of the key ring is matt. The Round Trolley coin (iron, nickel-plated) can simply be removed and reinserted after use. The heating vent key fits common heating vent valves.

A laser engraving on the trolley coin is your perfect advertising option.

Please be aware the trolley coin is round.
