I agree. I've used a few of their sets and the ones I've used are Taiwanese, and of Sturdy construction. The clip on the rollerball Big Ben is probably the best plated Cigar clip I've seen from any of them.What would make an inferior part? I have used pens from many suppliers and PSI has the same quality if not better on many kits. I have yet to see or have a problem with a PSI pen.
