The "Pilot Keyring / RBF" key chain is the classic among the key chains. The lettering, otherwise known only from aviation, is now also available as a stylish key holder. The embroidered and resistant polyester textile hangers guarantee you a long durability, are high quality and color intensive. The key ring made of metal is shiny silver and is already fixed.
In the real aircraft, the Remove Before Flight trailers hang on covers and securing pins that must be removed before the flight.
