Thank you for viewing. This is an illuminated, Showa-retro Christmas tree. It doesn't light up at all when plugged in. It sometimes lights up when the contact is good, but it's not reliable. Just having it decorated on the tree gives a nostalgic atmosphere and a feeling of nostalgia. There are 20 bulbs. I would be happy if someone who can repair it would be interested. I hope you can use it for parts or to replace the bulbs.
