Basically the copier is a standard current model e306 with special blue toner inside it. The blue toner is slightly faded like an old mimeograph machine. Toshiba choose blue so users could easily identify which pages could be erased.

The pen is from Pilot called a Frixion. The pen is not expensive and can be multiple colours.
Pages can be erased up to five times. There is a very slight residue image on the erased page. Each page that passes through the toner erasing device has an invisible mark placed on it.
People are generally amazed when they see it working.
At this time the cost with the eraser unit is approx 30% more than a standard e306. A few years from now, who knows?
