Product title: Besa Lighting 1JT-420187-SN 1X75W A19 Tessa Pendant with Blue Matte Glass, Satin Nickel Finish
Product description: Tessa has a classical bell shape that complements aesthetic, while also built for optimal illumination. Our Blue Matte glass is a dark primary blue pressed glass, with a white inner layer. This decor can add an edgy, classic, or contemporary feel to any room. When lit this gives off a light that is functional and soothing. The smooth satin finish on the clear outer layer is a result of an extensive etching process. This handcrafted glass uses a process where every glass is consistently produced using a press mold, keeping variations to a minimum. The cord pendant fixture is equipped with a 10' SVT cordset and an low profile flat monopoint canopy. These stylish and functional luminaries are offered in a beautiful Satin Nickel finish.
