The pens are actually awful. The design is great but the end caps come off when you put the top on the back of the pen. Every time. We throw away more defective pens than we are using. I wanted to order just one hundred and this is the exact reason. It's not fair to your customers to be stuck with this much junk. However, I do like the design and want to give out pens but I guess we need to see about getting samples before we order next time.
