The upper page is called CB paper, and only the next side is coated with CB drugs and is called CB surface; The next page is called CF paper, and only one side is coated with CF drugs and is called CF surface; The middle page paper is called CFB paper, and the upper side is coated with CF side and the lower side is coated with CB side.

The capsule size is only 3~7, the shell is made of resin, and the interior is covered with solvent oil containing colorless dye. When the capsule is destroyed by external force, the dye oil will flow out, if the CB surface is attached to the CF surface, the carbon-free carbon paper will flow to the CF surface to make the CF drug wonderful, CF drug is a coating containing color developing agent, binder, additives, color developing agent is mainly some resins and active clay.
