PROBLEM TO BE SOLVED: To prevent breaking of the lead of a pencil, and to prevent damaging and staining of a pencil case by a compass when colliding with the other article though a pencil holder and a partition are attached to the pencil case. SOLUTION: Since an article in the pencial case is fixed by a pressure sensitive adhesive, the article does not collide with the other article, and the pressure sensitive adhesive dose not transfer, so that there is no sense of incompatibility even when holding the pencial case by hand.
