I used this for about two years at work and have been storing it at home. I am selling it because I quit my job and no longer have the opportunity to use it. The entire band has deteriorated over time, and there is yellowing on the edges and the back. There are stains that cannot be removed and small scratches in the grooves of the button. * Also, the battery has died during storage, so please replace the battery before using it. * Since I cannot confirm the operation after the battery has died, I cannot guarantee that it will work after the battery replacement. (When I was using it, it was working fine.) Please understand that returns will not be accepted if it does not work. There is no box or instruction manual. Only the main unit will be sold. ・I have lowered the price as much as possible, so 【no price reduction】 is possible. Please note that I may delete comments asking for a price reduction. (If you purchase multiple items, I will deduct 100 yen from the total amount. If you would like to purchase multiple items, please let me know in the comment section. I will create a dedicated listing after confirming the stock.) ・I can only ship on certain days, so I cannot specify the date of arrival or shipment (e.g., "to arrive after ○ days" or "to arrive by ○ days"). ・I will not contact you after your purchase unless it is an emergency (I will reply if you send a message). Please understand this in advance.
