Another of the appearances to stand out of Manterola is that it believes in the synergies and in the collaborations with other artists and disciplines. It says that it exists a mutual enrichment in all maridaje. Proof of this are the exercises with artists like Gorka Larrañaga and Samuel Dougados, the project "UNYON" beside Ivory Jewellers and, more recently, the collaboration with the chef French , that has 3 stars Michelin, for the one who has designed the servilleteros of his restaurant of Paris and where in each table luce one of his sculptures.
