I purchased this a while ago, but it's been stored at home without being used. I'm selling it because I have no opportunity to use it. The cover (10 pieces) is unused and included. Instruction manual included. I have confirmed that it works. Please understand that I do not offer any warranty. Batteries are not included. I will only sell to those who agree to no claims and no returns. - Brand: OMRON - Model Name: MC-510 - Type: Ear Thermometer - Color: Blue Thank you for looking.
