Vintage Esterbrook DIP-LESS Fountain Well fountain pen holder No 444. Black bakelite top seated in clear lucite inkwell. I wasn’t able to remove the top, but didn’t want to force it. Great looking retro holder for any pen. About 4 3/8" diameter. Very good vintage condition with some minor signs of surface wear. See photos.
