Compact security alarm with shock and opening detection functions. I purchased this when I moved, but I don't seem to need it, so I'm selling it. The retail price varies, but it exceeds 2,500 yen including shipping on online shops. It's been less than a year since I bought it. For those who need it! I will protect it with air-cushion packaging and ship it. - Brand: ELPA - Model: Slim Alarm - Functions: Shock detection, opening detection - Power supply: Lithium battery CR2032 - Size: Compact design - Features: Easy operation, powerful alarm Thank you for looking.
