This Tiffany style lamp is hand-crafted using the same techniques that were developed by Louis Comfort Tiffany in the early 20th century. Each piece of glass is hand cut to the perfect shape and size, wrapped in copper foil, and soldered together to create a truly unique piece of art. Made with 108 pieces of hand-cut stained glass. Pull chain switch for easy operation. Requires one 40W E26 medium base type G bulb (Not Included). Our lamps are fully compatible with CFL and LED bulbs. Shade colors will appear darker and less vibrant when not illuminated. The handcrafted nature of this product creates variations in color, size, and design. If buying two of the same item, slight differences should be expected. This stained-glass product has been protected with mineral oil as part of the finishing process. Please use a soft dry cloth to remove any excess oil.
