New Set of 4 Wireless Window Alarms Baby Toddler Kid Safety or Burglar Alarms

New never opened, 4 wireless window alarms. I use these exact ones and when they are triggered they are ear piecing. I initially bought too many. The batteries are able to be changed. They adhere to your window or door with a sticky adhesive which is already on the alarm. These are great for child safety and also on the flip side for notifying you if an intruder may try to enter your home. See the picture section for item details.
