The Tri-Band pen being available in BLUE INK and with a Parker-type refillable cartridge were both a plus. I would like to see more options with BLUE INK. PLEASE kindly mention in the catalog description whether a pen is refillable and if so, whether it is Parker-type. We always have to order a sample or check with the salesperson, who sometimes don't know the answer (they had to check with Production this last time) which takes extra time. The clip on the Tri-Band pen is solid, not like some pens which have weak clips that get bent out of shape easily and no longer keep the pen securely in place. Although the Tri-Band pen looks great, I must say that, as we have used the pens, we have noticed that the edges where the metal bands meet the rubber parts are just sharp enough that they can irritate the fingers. We will probably go back to the Wolverine pen if we order in the future as it has a continuous rubber grip (and fewer parts to lose, too!). Thanks for always improving!
