A group of three Euros for my business partner. Yes, there are no clips, that what he wanted. The blanks are unknown, they were in a box of materials I bought from another turner, not labeled. (Need to work on photo depth.)
There are three very good pens. The fit and finish is great. Try laying the pens more across than up and down for better depth of field. If you can keep the subject in the plane of the sensor the depth of focus is less critical.
