These kaleidoscopes come without assembly instructions. They also come in two different sizes: 4 inches and 7 1/2 inches long. Unfortunately, the outer decorative paper is the same size, 4 inches long. It doesn't do justice to the longer size. I cut the paper for the longer ones to make them passable. The only way to manipulate them is to transform them as a whole. If you try to twist the end while holding the beads it will fall off. Pretty thin at best and definitely not worth $3 apiece!
