To provide an attaching utensil by which the box does not need to be held by hand so that the box may not move when tissue paper is taken out from the tissue paper box, and the tissue paper can be pulled out by one hand.

This attaching utensil is formed into a box which is one size larger than the tissue paper box 9 so that the tissue paper box 9 may be housed. Then, on the side surface 5, a take-out/put-in port 8 is provided, and the upper surface 2 is formed into a widely cut out opening 7. On the bottom, a double adhesive coated tape or the like is provided to prevent the attaching utensil from moving.
