The mosaic is exceptionally large, the size of one chip is 2.5 cm, while the chips do not have pins on the legs (i.e. sharp parts) and this makes the mosaic safe for the little ones. Chips are put on the convex parts of the tablet. The tablet is plastic, flexible and, alas, rather fragile. There are so many chips to fill all the slots of the tablet, letters and numbers are repeated at least 2 times, and the main vowels are repeated three times. In addition, there are mathematical signs and punctuation marks. 110 chips in four colors. Tablet size 25x31cm
