The Red Number 2 design was planned to be one of three new color variants that sold along side the classic original yellow pen. We premiered the pen at trade shows, and even went so far as to have printed materials promoting the product. But at the last minute we decided it would dilute the uniqueness of the original yellow version, and canceled our plans for its release. This retractable roller ball comes with a black 8126 roller ball refill. This pen was only sampled and once they are sold, no more will ever be available for sale.
