Set of 2 security alarms that sound a 125dB alarm when a window or door is opened. - Set includes: 2 pieces - Color: White - Usage: For windows and doors - Volume: 125dB - Product name: Sma Alarm Thank you for looking! m(_ _)m I accidentally purchased these and am now selling them. There are 2 sets of 2. One box has been opened, and the box is damaged in places (photo 5), but the contents have not been used at all. With so many unsettling things happening lately, how about it? I purchased 2 sets for 4480 yen. I will also accept the purchase of one set.
