Used Philips Hue Dimmer Switch Wireless Remote. Purchased in November 2020 from Amazon.co.jp and used as a remote for Philips smart bulbs. The outer box has been disposed of, so this is a sale of the main unit only. I am selling this because I have replaced it with a new Philips Hue dimmer switch. If you have any questions, please feel free to ask. I have other items for sale as well, so please consider them.
