Used Sesame 4. I no longer need it as I've upgraded to the new model. Although discontinued, information remains on the manufacturer's official website, and the original price seems to have been 4,989 yen. It works without any problems. There are no major scratches. The product contents are as follows: * Sesame 4 main unit * Battery (new, included with the new model) * Sesame 4 screwdriver (1) * Metal base adapter (1) * Metal base adapter screws (4) Please prepare double-sided tape separately for attaching it to your door. 3M VHB (super-strength type) was included as standard. If it doesn't fit your home's thumbturn, you can request the manufacturer to create a perfect fit using a 3D printer for a fee. That's all.
