This is the largest mixing bowl by Pyrex in the Cranberry Originals pattern. It is 11" wide. Originals was produced in Cranberry beginning in 1997 and is now discontinued. This bowl is the 4L, also known by the number 326. It is in very good to excellent condition with no chips or cracks. The bowl has a few utensil marks. I also have the three smaller bowls in the set listed separately.
