These items are new. Open box don't have box take 9 volt battery are very accurate. These are professional equipment. No cord just 9 volt battery instructions are on the back as shown in the picture. He's a very professional thermometers. I have more than one. Plenty without box will be wrapped up in bubble wrap and shipped in a box also, when opening up the unit they will be a little hole on the side did you just stick a needle or paper clip in the hole and it will release the battery to open? I just thought I'd put that in there for you also in the picture it's just missing a sticker but they are new items
