The Regenborgen paperweight by Fundamental Berlin captivates the eye with its shiny surface that sparkles in all the colors of the rainbow when the light hits it. The paperweight is hand-cut from crystal glass and coated with a special chromatic film to highlight the colors of the spectrum. The luminous paperweight keeps documents, letters, magazines and other important papers in the office well-organized, but also adds an elegant glow to the interior as a single, shimmering decorative item.
