This is a brass kaleidoscope. I don't know how long it's been in my home. The heavy brass tube gives it a retro feel. The patterns that appear are completely different because the places where light enters (the bottom and around the tube), the shapes of the pieces inside (round beads and fragments), and the shapes of the mirrors are all different. It's difficult to capture in photos, and I can't fully show you, but I've included some photos. Please check the photos for the size. There are no noticeable stains or scratches, but it is an old item, so I would like those who understand this to consider purchasing it. Please read my profile.
