Milk Glass Flower Frog

Very unique milk glass jar with a wire mesh cage frog, designed to hold flower stems upright and in place within.  

Historically, flower frogs were a common tool for florists and amateur flower arrangers before the invention of floral foam in the mid-20th century. They are typically made from materials like glass, ceramic, or metal. The name "frog" is believed to have come from the way these devices sit in water, similar to how a frog lives in water.
