The click pens are built around a Schmidt click mechanism. There are two basic styles. The “Long Click” and the “S Click”series.
The Long Click style (shown above) is based on an 8mm tube but it can be customized and built on a 3/8 or 10mm as well. Contact me for a quote on larger Tube sizes.
The “S Click” series pen below (s2004) is built on a 10.5 mm tube.
We have three or four different lower units that can be made into click pens. Or if you have a design we could build it as well..
