Screwdriver with replaceable tip

I designed a promotional item for Fillamentum with the aim of putting it to practical use. Thanks to the interchangeable tips, the use of the screwdriver is really wide. The spare tips are stored directly in the screwdriver body and are therefore always at hand. Changing the tip is simple, quick and can be done by everyone. In my opinion, the screwdriver in corporate colours is exactly the type of promotional item that will please every corporate partner.
