This pretty white milk glass bird seed cup will complete your vintage cage. The cup has a 3/4 inch tab that fits beneath the bars on a wire cage and holds seed for your bird to enjoy. The cup measures 3 inches tall by 2 1/4 inch wide and the opening for the bird to access the seed is 1 1/2 inch in diameter. The cup is not marked as to maker. There are no chips or cracks. There is very minor roughness along the opening from use. This is a lovely cage accessory.
