The Pyrex 444, 4Qt. and 442, 1/12 Qt mixing bowls are a vintage set originating from America in the mid-20th century. These round bowls feature a glossy finish and a classic mid-century modern style, perfect for all occasions. Made of milk glass with a brown color and vintage pattern, these original PYREX bowls are a two-piece set that includes a bowl with an impressed backstamp. Care instructions recommend hand wash only, and these decorative cookware pieces are a timeless addition to any kitchen collection.
