Automotive accessory manufacturer Richbrook has introduced its Magnetic Never Lose Valve Caps.
They have a strong yet small magnet hidden within them and the manufacturer says that if they are stuck to an adjacent panel when removed they will never be lost.
The caps have been tested in such situations at motorway speeds.
Caps are precision machined in aluminium and are finished in either black or silver. They have a corrosion proof nylon core and come with a keyring tool for easy removal.
