I purchased this item in preparation for childbirth, but I will be selling it as I ended up using a different baby sensor. I opened the package and turned it on to confirm it was working, but please refrain from purchasing if you are concerned about this. It has never been used, and I have not put it on my child. * I will ship the contents wrapped in cushioning material without the outer box. * Instruction manual, etc. will be included. Thank you for looking.
