Thank you for viewing. I used this under a baby futon for about a month starting in March 2025, and have since stored it at home. The box, instruction manual, and all accessories are included. Operation has been confirmed. *Although operation has been confirmed, please use it after checking the operation according to the instructions. There are some scratches on the sensor panel (see photos 3-4). There is dirt on the battery compartment lid of the control unit (see photo 5). Other than that, there are no noticeable scratches or stains, and it is in a clean condition. Batteries are not included. - Brand: BabySmile - Model Name: BabyAlarm E-201 - Accessories: Instruction manual, control unit, sensor panel, strap The box will be wrapped in bubble wrap and placed in a plastic bag, then shipped in a paper bag with simple packaging. Please understand that this item has been stored at home and has been inspected by an amateur. If you have any questions, please ask before purchasing. Thank you.
