Doesn't look like they sell the exact same pen. I also wonder why that is when they have one for all the others of the recent models. Needless to say, I am able to use my previous tablet's pen with this tablet. My previous was the original "Wacom Bamboo Pen" tablet. So maybe they're all interchangeable if they're from a bamboo tablet. But I know that one for a fact, is compatible with the Splash.
