My ex-boss used to get corporate gifts for our clients, associates and etc. Many of these have to be very expensive and impressive gifts because they are given to high profile people.
So, buying pens is one of the option because it is a status symbol for these men and women as they use it often to sign important documents. It says a lot about the person if they whipped out a nice and expensive pen. Pens with beautiful design, expensive finishings and lasting quality are hard to find nowadays. But you can surf over to the link and have a look at what are available. Hopefully, it will solve your headaches of finding good corporate gifts as well.
