To save trouble of buttoning by providing a rough shape with the center of an elastic hard material with a needle shape on its ends, by putting the material into button-holes and into a catch with a rough part engaging and by covering the catch.

Rough shape 2 is provided with two parts of the center of elastic hard material 1 with needle shape 3 on its ends. The inside of catch 4 is equipped with rough shape 5, which engages with rough shape 2. The needle shape 3 is put into the holes of the catch 4 so that rough shape 2 can meet rough shape 5 after it is put into the buttonhole 7. The needle shape 3 sticking out of the catch 4 will be cut off. Lid 6 covers the catch 4 so that the cut part will not touch the skin. When the buttonhole 7 has four holes, two of the elastic hard material 1 are used. This tool and scissors allow easy buttoning even without a needle or a thread on the spot.
