PROBLEM TO BE SOLVED: To provide a case also capable of being used as a direct mail enabling a receiving person to have an interest against it, enabling the receiving person to confirm its content positively and further capable of being used for a long period of time. SOLUTION: This case is equipped with a pair of case composing materials 10 and 20 having the same shape to each other while constituting a hollow box body through their combination. Each of the case composing materials 10 and 20 is constituted such that it is integrally formed into a U-shape with a resin having a transparency in such a manner that the side plates 12, 13, 22 and 23 extend substantially in a vertical orientation from both opposing sides of square central plates 11 and 21 against the central plates 11 and 21. An end edge of each of the case composing materials 10 and 20 is applied as a slant surface inclining at an angle of 45°as it approaches toward inside the case composing materials. The other case composing material is slidably fitted with respect to one composing material to constitute the box. The other case composing material can be held at a desired position with respect to one composing case material and each of the side plates of each of the case composing materials is formed to be slightly inclined in a direction where they approach to each other.
