Can you refill it or is it disposable?

You can refill this, with either a Pilot converter or with a Pilot cartridge. Pilot uses proprietary converters and cartridges.

Can the Con-40 converter be used in this pen?

The Con-B, Con-40 and the Con-70 can all be used in the Pilot Kakuno.

Is the ink waterproof and archival?

Pilot Namiki ink, which is what comes in the cartridge with the pen, is not waterproof or archival. For replacing the ink in the cartridge with permanent, archival-quality, and water resistant ink, I recommend buying Diamine Registrar's Blue-Black Ink, a 3ml luer-lock syringe, and a blunt-tipped dispensing needle at least 3 inches long. 1. Gently insert the cartridge (JUST BARELY) into the pen, only enough to open the cartridge. Pull it back out, rinse the ink out of the pen, and empty the ink from the cartridge with the syringe and needle. Dispose of the ink, and rinse the cartridge, syringe, and needle with clean water. Shake the water out of the cartridge. You can dry it out with a Q-tip if you don't want you new ink diluted at all. 2. Withdraw ALMOST 1ml of the Registrar's Blue-Black Ink with the syringe, and fill the cartridge with it. 3. Insert the newly refilled cartridge into the pen, gently but firmly. Set the pen nib-down in a cup , with the cap on, for 5-10 minutes, so the ink can saturate the feed and reach the nib. And don't press too hard if it's still not writing yet. Give it some more time.

What size cartridge does this pen take?

The PILOT KAKUNO FP takes a PILOT NAMIKI IC100 FOUNTAIN PEN INK CARTRIDGE or a PILOT CON 40 converter.
