A highly sought after red Pyrex nesting mixing bowl. 8" diameter. The bowl is in very good condition, with relatively minor signs of wear for its age. While I am no expert, this bowl appears to be older than the larger green Pyrex bowl among myproducts. There is no logo on the bottom of this bowl, and there are minor design differences from the green bowl. The two bowls do nest. Great addition to the vintage kitchen. Go ahead and use it. My 91 year-old mother is still using hers.
