This is a vintage Pyrex glass, nesting mixing bowl in the Butterfly Gold pattern.  It is a #401- 1 12 pint size.  It stands 3 1/4 inches tall and it measures just over 5 1/2 inches across the top. There are no chips or cracks in the bowl and the color is in beautiful condition.  Let me know if you have any questions. The bowl will be shipped quickly and will be packed with great care.
