This is a TOPLAND ETIQUETTE CHECKER, a breath checker that detects both bad breath and alcohol. ◼️Main Features: The main feature is that it combines the bad breath check function and the alcohol check function, which were previously separate, into one device. It has two operating modes: bad breath mode and alcohol mode. When you breathe into it, it displays the level of bad breath or alcohol in 6 stages. The device is equipped with a gas sensor that detects the components contained in your breath. In alcohol mode, in addition to the 6-stage display, it can also display an estimate of the amount of alcohol in your breath, up to 0.5mg, in 0.05mg increments. It uses two AAA alkaline batteries for power, and the battery life is approximately 120 uses. The lifespan of the sensor is unknown. Body size: 110 x 30 x 18mm (width x depth x height) Weight: 52g including batteries (Batteries not included) There are some scratches on the LCD screen, but overall, it is in relatively good condition. It has been cleaned and disinfected with alcohol. Instant purchase is welcome. It will be shipped in simple packaging using recycled materials. Please note that the shipping method may change depending on the circumstances. I will not respond to excessive price negotiations. No-comment purchase is OK. #BadBreathChecker #AlcoholChecker #BreathChecker #EtiquetteChecker #TOPLAND #TOPLAND #TOPLAND_BadBreathChecker Item k165.5.33.1219.2.5
