Stunning Rare Pair Of Vintage Sterling Silver Ballpoint Pen & Pencil Set. They both work perfectly. They feature a wonderful simple lined Ard Deco style design. They both have a twisting system to operate the ink and the lead, the top half pulls off to reveal and unused eraser on the pencil. I am not sure how you change the lead or the ink refill on these but recommend that you seek advice before you try as not to damage anything. They are fully hallmarked with the makers mark "S&T", the lion passant, the London assay mark and the date letter "r" for 1972. They each measures approx 13.0 cm in length. They weigh 42.1 grams together. They are in really excellent condition and come in the original inner part of their fitted case, I don't have the rest of the case the inner part has protected this beautiful set from any damage.
