A tumbler pen is provided to maintain a standing position even if it is placed carelessly to prevent the tumbler pen from falling from a table or being lost and to prevent hardened skin in a user's hand. A tumbler pen includes an elastic body gripping member and a pen member. A penetrating hole having a predetermined diameter is formed along a central axial line inside a body(111) of the gripping member. A weight body(112) is installed on one end of the penetrating hole. The gripping body contracts when being gripped and returns to its original shape when being released. The pen member is inserted and fixed into the penetrating hole of the gripping member. A penpoint portion is installed on one end of the pen member to come in and out of the penetrating hole according to the rotation to the left and right. |
