In order to guarantee your use of LAINO products in the best conditions, we indicate a PAO (Period after Opening) on the products. This symbol represents a box with an open lid and a figure (or number) followed by a “M” that indicates the number of months of the recommended shelf life of the products during which they can be used under the best conditions after their opening. For products that can be conserved at least 30 months from their date of manufacturing, the PAO is not mandatory. In order to ensure the perfect preservation of your LAINO products, it is best to close them after use and not transfer them to another container.
