Purchased in January 2026 and used once. I am selling it because I no longer have the opportunity to use it. Since it was only used once, the battery still has charge. It is in excellent condition with no scratches. Operation has been confirmed. It will be thoroughly disinfected and shipped anonymously within 24 hours. ★Domestic Genuine Product★ ■ Basic type women's thermometer ■ Large character display that makes it easy to check the measurement status and temperature results ■ Flat sensor that fits under the tongue and does not slip ■ Comes with a convenient basal body temperature chart ■ Specifications ■ ・Power supply: Battery LR41 x 1 ・External dimensions: Width 19.6 x Length 129.7 x Thickness 13.2mm ・Body weight: Approximately 13.0g (including battery)
