THE CLICK BUTTON

With the click button you get a working ballpen mechanism in a compact form. No support is needed. And with the following assembly video you are good to go (video contains old parts).

To ensure proper clicking head for these points: 

• Remove brim (if used) of part 06 properly
• Grind all contacting surfaces
• Grease these contacting surfaces (e.g. use face care cream)

Have fun.
