The marbles are sourced from all over the world in myriad colours and arranged thematically into boxes corresponding to different “universes”. Each Billes & Co. box of marbles is a work of art in itself, hand painted by Manu in their French workshop. The marble boxes are made with all natural and recycled materials, presenting an eco-friendly toy that will inspire children’s imagination and develop their motor skills. If you’re looking for kids’ toys, these Billes & Co. boxes are the perfect gift for children as well as a unique home décor piece.
