I just started making pen a while back,so I'm no expert.I really like those,great looking pens.I took my pens to a campout recently and it was suggested by a good lady friend of ours that the ladys she works with,not only likes the slim pens like those,but don't really care for the clips,as they are carried in there purse or check books and don't need the clip.I too have made some without the CB and seems a lot of folks like then also.
