The Marxman marking tool uses a propellant and a coloured pigment for marking fixing holes, this makes the marxman very useful for marking through deep items that cannot normally be marked using a traditional marker pen, even a long reach marker pen. Currently the marxman is available for about £8 at screwfix or on ebay. [ Ссылка ]
The marxman pen is famous as it has won several awards and has been on Dragons Den, there are currently two versions available, the standard marxman and the deep hole marxman.
