Papier mâché is a natural material consisting of paper pulp and glue. It’s surprisingly versatile and strong. Although we provide the material with a protective coating, papier mâché remains sensitive to water. Do not pour liquid into a vase made of papier mâché. Dried branches won’t harm. If you want to put live flowers in a vase, place a waterproof container in it first. We also recommend that the papier mâché be dusted regularly with a dry or slightly damp cloth. Avoid excess moisture, as this will cause damage.
