Toys for children are often made for a reason, but with the aim of developing their intelligence, hand motor skills, logic, spatial thinking, and so on. Modern toys can do a lot and surprise even adults. One of these are transparent balls made of a special polymer. They are called Obriz after the brand name of the same name under which they are produced. This is not a new toy, it appeared in the late nineties and the peculiarity of the balls is such that when immersed in moisture, in other words, in water, they increase in size. For a kid, this is a real miracle - a ball that grows in size right before your eyes, and then you can play with it. In Orbeez Jigsaw you have to collect a picture with a whole bunch of these balls.
