Description:

100% brand new and high quality!
A paper coated with an acid developer on the front side and a microcapsule containing a colorless leuco dye on the back.
When the paper is overlapped, the microcapsules are broken due to mechanical pressure, and the colorless leuco dye overflows with acid and develops color to form an image.
The carbonized surface coating is uniform, bright, with clear copying effect and continuous lines.
It can be reused multiple times.
This paper can be used in an overlapping manner and used as a ticket.
