Crafted in Spain of durable recycled glass with rustic cork stoppers, our gift set of stackable oil and vinegar bottles display a beautifully subtle blue-green tint. Saving space on the counter and displaying with flair at the dining table, each bottle features a universal design that allows either to be placed on top. This upcycled-glass gift set is worthy of presenting the finest artisan olive oils, balsamic vinegars and gourmet dressings.
