Each Inconcreto lamp is unique. We don't use molds; we start with molds, from which the lamps are shaped. The composite used is more resistant than regular papier-mâché because natural materials are added, making the product more durable yet still extremely lightweight. Each lamp is hand-painted using natural pigments, various types of water-based paints, and, most importantly, is protected, both inside and out, with water-based protective coatings or natural beeswax. This allows for extreme resistance to water splashes and stains and long-lasting durability; its special protective barrier ensures optimal results with a simple wipe with a sponge or microfiber cloth soaked in water or neutral soap. Up to 250V (Europe/UK Standard).
