Vintage CROSS 10K Gold Filled slender ballpoint pen in retail box, CROSS 10K

...rolled gold writing gift for student #4502 A slender CROSS ballpoint pen, in the original chocolate brown plastic retail box, with card sleeve, marked model number 4502. With a little OK logo to the top, and marked "-CROSS- 10KT gold filled USA, electroplated emblem" The pen is a little more slender than a ´regular´ pen and it works well. The pen writes smoothly, but despite the black end tip, currently has a blue filling. Cross has made high-quality writing utensils since 1846 and backs this up with a perpetual lifetime warranty. There is a little booklet about the warranty underneath the pen, inside the box (sorry not pictured) "Classic Century 10 Karat Gold Filled/Rolled Gold Ball-Point Pen. Preferred over gold plate for its greater gold content and wearability, our 10 Karat Gold Filled/Rolled Gold finish on the cap and barrel of the Classic Century ball-point pen complements the elegant and timeless design of this American icon. An American classic-since 1946. An icon of mid-century modern design, this is the Cross pen everyone knows and loves. We may have come a long way since then but this nostalgic favorite spans sixty years of poems and letters, good wishes and thank you's."
