Decorative design RGB full-color digital desk clock. - Model Name: RGB Full Color Clock - Color: Red light - Design: Decorative design - Product Type: Desk clock - Accessories: Storage case Purchased November 20, 2024. Assembled and operated, including setting the time. This is a Nixie tube-style desk clock assembly kit. It's pre-assembled and power-tested. It works without any problems. Even when the power is turned off, a button battery is built-in, providing a backup function that remembers the time, so no resetting is required. This is only a backup function, so the time will be lost when the power is turned off. Mode switching allows for adjustment of brightness, color tone, and various patterns. Please be careful, as connecting it to a power adapter other than a Type-C 5V1A power supply may cause a malfunction. There is an instruction manual, but it's only in classical Chinese and English, but you should be able to use a translation app. The Google Translate app's camera function can translate it into Japanese. I will ship it assembled and wrapped in cushioning material. I will include the separate roof part, spare parts, and extra screws. This is assembled by an amateur, so please only purchase if you don't mind.
