This is a Tombow Variable. I didn't like the feel of it and felt it wasn't practical, so I'm selling it. It's the early model with a metal core tank. I haven't used it much since I bought it. There's a mark on the base of the nib where the cap was attached, but otherwise, there are no scratches or stains. The price is firm. I confirmed the core adjustment. Sorry, the third picture is blurry.
