PROBLEM TO BE SOLVED: To print a hidden letter, a mark or a picture in a hidden part of a natural raw material having a split line and to use it for fortunetelling and prize contest. SOLUTION: A printing paper (2) is inserted into an arbitrary position of a split (3) of half-split chopsticks main body (1) by opening the split (3). If the printing paper (2) can not be inserted into the split (3), a slit into which it can be inserted is provided in advance. However, when the printing paper (2) can be inserted by opening the split (3), the slit is unnecessary. A heat transfer film is used for the printing paper (2) and the letters, the picture, the mark, etc., can be printed into a free shape by inserting it into a position shown in the figure and heating it from the outside to perform heat processing. Degree of the heat applied from the outside is different by the size of the raw material and other elements. |
