Window Fit Alarm, Dark Brown, 2 pieces per pack, includes 2 CR2032 lithium batteries. The box was opened to check the contents, but the items are unused. The box is slightly torn from opening, but there is no problem with the product itself. I am selling these because I will not be using them. They will be shipped via Yu-Packet Post Mini. New, unused item. Please feel free to ask any questions you may have.
