HITACHI Men's Shaver Charger Charging time: 5 hours - Brand: HITACHI RM523 Made in 2016 There is no instruction manual, so please check the Hitachi website. I only tried this once, but it didn't suit me, so I'm selling it. Due to long-term storage, there are slight scratches like in photos 4 and 5. They are not noticeable, but please refrain from purchasing if you are concerned. Operation has been confirmed.
