Cobi will produce a range of building sets based on the girls' property.
A range of Winx Club Building Blocks will hit toy shelves in autumn 2013.
Poland-based Cobi – one of the biggest manufacturer of construction blocks in Europe – will produce the series of building sets.
It has signed a deal with Rainbow, owner of the girls' property and TV show Winx Club, which airs on Nickelodeon in the UK.
A statement read: "The production of Cobi's blocks is European and guarantees the high standard ABS, and strong play value which they have succeeded in achieving with other brand partnerships like Jeep, Boeing and McLaren.
"The magic and dynamism of the Winx world will provide the basis for a huge range of engaging collections, which Cobi aims to release from autumn 2013."
