Thank you for viewing. This is a white noise machine. I used it from when my baby was a newborn until about one and a half years old, but I'm selling it now that my baby has outgrown the crib. For my second child, I used it every night from when they were a newborn to help them sleep in their crib for sleep training. It's said to have a calming effect, and I think it helped them sleep relatively well. It was easy to take with us when we traveled, and it was also useful as a light when changing diapers or feeding milk at night. It charges with a Type-A cable, but I used a plug to charge it from a wall outlet. I will include the plug with the machine. Brand: dreamegg Model Number: HFD-W11 Input Voltage: 5V Input Current: 1A Included: Main unit, charging cable, plug Purchase Price: 3699 yen I don't think there are any noticeable stains or scratches, but please understand that this is a used item. *Individual babies may react differently, so I cannot guarantee the effect.
