On Monday, May 25, 2026, the 23rd Review of Student Cooperatives of the City of Zagreb was held in Zrinjevac Park, in which our school cooperative “That's it!” also participated. The cooperative was represented by Sara Pajalić from Grade 5c and Luka Rubinić from Grade 6 (MYP1), under the guidance of their mentor, Ivana Devernay Cimić. Among as many as 48 student cooperatives (from primary and secondary schools and various centers), our cooperative achieved excellent results and, with its unique products, impressed both participants of the exhibition and passers-by.

Our product is a collection of natural, handmade paints called Pigmentarium, which includes a range of coloured pigments, watercolours, dry pastels and chalks, as well as wax crayons. We enriched the collection with educational colouring-book illustrations of the plants from which we obtained the pigments through a salting-out process, and then used them to create our own paints.

The presentation of our Pigmentarium collection at the exhibition can be viewed in the photo gallery.
