1, 311 must be cut, but since the sealing members 21, 31 are colored differently from each other, the cut portion of the box sealing tool 210 is repaired using an adhesive or the like, and the cut is concealed. To do so, it is necessary to reproduce the color of the cut portion. However, it is difficult to reproduce the color of such a cut portion, and it is not easy to hide traces of the cut. Therefore, since it is not possible to reliably conceal the fraudulent activity, it is possible to detect the fraudulent activity at an early stage and to suppress the fraudulent activity.

The coloring pattern of the box sealing member 210 only needs to be different in the color of the sealing members 21 and 31 opposed to each other. , Red), and all the sealing members 31 of the sealing unit 30 facing the sealing unit 20 may be colored in another color (for example, green). Further, each of the four sealing members 21 of the sealing unit 20 is colored in a different color, for example, red, blue, yellow, or green, and the sealing member 31 facing the red sealing member 21 is replaced with a green or blue sealing member 21.

Since the wire members 212 and 312 made of wire material and the like are provided around the grid at substantially equal intervals, the box sealing tool 210 is cut using a tool such as a saw to open the substrate box 1. Then, the teeth of a tool such as a saw are hooked on the wire member 212 or the wire member 312. Therefore, when cutting is performed with a tool such as a saw, the portions of the sealing members 21 and 31 other than the cut portions are broken by the wire members 212 and 312, and traces of the cutting can be left. It is not easy to repair the sealing members 21 and 31 that have been destroyed in this way to conceal traces of cutting, and it is impossible to reliably conceal fraudulent acts. Therefore, the misconduct can be detected at an early stage, and the misconduct can be suppressed.
