I first encountered these pens in a convenience store in Barbados -- we purchased them because they were the only ones we could find at the time and needed to make a shopping list. BEST. PURCHASE. EVER.I love them -- rich gray-black from the black pens, deep blue and vibrant red. Smooth writing and extremely long-lived.So glad I was able to find them on when I got back to the states. Fantastic product for a great price. My husband loves them so much he has me order them for his business too.
