The defining characteristic of these flutes is the "filament" stem, which is a hollow, colorful, glass stem that contain a single-colored red strand inside. Pier 1 Imports, founded in 1962, specialized in selling imported home furnishings and decor. The company's business model was based on importing unique and exotic goods from around the world, which included a wide variety of handcrafted glassware, much of which was mouth-blown. While Pier 1 didn't manufacture the glassware themselves, they curated a wide range of designs. This means that a specific style, like the "filament stem" flutes, was likely produced by various artisan glassworks for Pier 1 over a period of years. These glasses are in perfect condition.
