Around the year 2000, transparent iMacs were popular, and this is a paperweight, memo stand, and card holder with a similar feel. Looking at the back, it seems to be made in Denmark. It's quite sturdy, and steel pellets are inside. When you shake it, it makes a beautiful sound, so it can also be used as an egg shaker. I think it's a rather rare item. The diameter of the base is about 6 centimeters, and the height is also about 6 centimeters.
