[About the Product]
*Quoted from manufacturer information*
1. Detects intrusion in two ways (double security)
? Detects glass breakage: Detects impact and vibration when a burglar breaks a windowpane.
? Detects window/door opening: Detects when a window or door is forced open (reacts when the main unit and the long, thin magnet part next to it separate).

2. Loud alarm
When an anomaly is detected, a loud alarm of approximately 90 decibels (at a distance of 1 meter) sounds, alerting those nearby and acting as a deterrent. This is comparable to the sound level of a police car siren or a noisy factory.

3. Other features
? Ultra-thin: Its thin profile makes it less likely to interfere with closing windows and allows for a neat installation.
? Easy installation: Simply peel and stick using the double-sided tape on the back.
? Battery life: Uses a lithium battery (CR2032) with a long battery life of approximately 3 years.

This is a standard security product commonly used for preventing burglaries at home and enhancing security for balconies and windows.

[Warranty, etc.]
As some time has passed, the one-year warranty has expired.
Although it is an unused item and I believe it works, I have not personally tested its operation, so I cannot guarantee its functionality.

I apologize, but this is a no-claim, no-return sale. Please only purchase if you understand and accept this condition. m(_ _)m
