I'm so glad that I found these Pyrex replacement lids for the glass storage bowls. I've had the bowls for many years and made the mistake of putting the lids on the top rack of our dishwasher. This caused them to wear and crack over time due to the heat in the wash cycle. Now I don't have to throw out the old glass bowls in the recycling bin or get stuck with bowls having no lids. Pricing was reasonable for the 4 replacement lids. It's good to know that I will have extra, if needed in the future.
