UMAGE Acorn Lampshade
Three parts — a silicone cup, a glass shell, and a metallic kernel — interlace in Jacob Rudbeck's forest-inspired lampshade.
Inspired by the small, delicate acorns found at the roots of majestic oaks, the shade leads your thoughts to the forest. It is made in China for UMAGE's Copenhagen studio and may be small, but it holds a bright world inside.

Common Questions
Is a bulb included with the lampshade?
No — the Acorn lampshade takes a light source of max 15W LED with an E27 / E26 base, sold separately. UMAGE's bulb recommendations sheet can help you choose the right one.
How do I care for the shade?
Dust with a soft, dry cloth or a soft brush. Handle feather and textile shades gently and keep them away from moisture; never use liquid cleaners on paper or feather shades.
