This is a printing pen for printing letters, numbers, symbols, characters, figures and many other things. The printing pen has a symbol roller - which can be exchanged in many ways - for printing in various colours. It can be produced in different sizes and colours. It is a great learning aid, for example for pre-school children. Using the pen makes it easier for the children to learn letters, numbers, characters, etc. The printing method comprises rolling the symbol roller which automatically also rolls the piled roller. The latter takes the ink from the felt rod which is connected to the ink container. The piled roller has funnel-shaped recesses on both sides and is attached, in turn, on funnel-shaped tips. Due to this rolling method, the wear of an axle is avoided and a finer rotation possibility is guaranteed. The symbol roller is attached as in the case of the piled roller, but with a separate covering which can be exchanged as desired.
