SPECIAL PROJECT: MARé the customisable straw in #plasticfree steel

With Corporate Social Responsibility and the environment in mind, Poli has created a new AISI 316 stainless steel straw to replace traditional plastic food and drink straws. "We had been looking for an object with a specific use and that, at the same time, could be a way to help us drive #plasticfree change. But we also wanted it to be beautiful, completely safe and Made in Italy!”, says Claudia Poli, Poli Srl CEO. MARé is a high-end product, that can be customised or engraved, and with features that make it unique in design and quality.
Project recognised by the CONFINDUSTRIA Study Centre - Italian BBF product “Bello e ben fatto” (beautiful and well done) to support Made in Italy and the products that convey its values.
