Instruction
Cut very thoroughly a crib sheet with dimensions of approximately 10 cm x 3.2 cm
The sheet should ideally wrap around the entire pen. It cannot overlap. Thanks to this, the blue case will closely adhere to the pen body


Adjust the crib sheet on the pen.
It will be much easier to put it in the • semi-transparent case.
Bend the sheet at the end of the pen
and put it into the case from the cut side.


Slide the case almost to the end of the pen
Please ensure that the crib sheet is well cut and does not overlap. Then you will be able to put the case to the end and it will closely adhere to the pen without any problem.
