Waterman Pen Refills
I have a Waterman ballpoint that friends gave me. The refills skip. I don't know if they overstayed their shelf life, or if the ballpoint tip is a manufacturing flaw. My guess is the latter, because the original ink cartridge, that came with the pen, began to skip pretty quickly after I started to use the Waterman. Perhaps it's an issue you could pass along to the Waterman company. I won't buy another Waterman product.
