I ordered 500 of their soft touch Paragon pens about 4 years ago. We have used and given them away but noticed about 5 months ago that a lot of the pens were not writing properly. We ended up with about 250 pens that don't write so I guess after a few years the ink becomes bad. I called customer service and they said their warranty is good only for one year so there is nothing they could do (no credit, no ink refills, nothing). So my advise is do not order large quantities of their pens if you don't think you can use or give them away within one year - you may end up just throwing them away like we had to. I have pens from other companies that are 10 years old and work fine so this is definitely a quality issue.
