Unused Showa era deadstock Pyrex Iwaki heat-resistant glass container, gold rim, microwave safe

This is a set of two unused, heat-resistant glass containers from the Showa era, designed for detoxification.
(☆Note: While these heat-resistant glass containers are safe for direct use in ovens and microwaves, please refrain from using them over an open flame.)

This is a collaborative product between Iwaki Glass and Pyrex. The rims and handles of the heat-resistant glass are decorated with gold accents, but due to special processing, they can be placed directly in the microwave. How about using them for microwave steaming or oven cooking?

This set includes two containers: one with handles and one bowl. The lids are interchangeable.

The condition is that while there is no box, these are beautiful pot sets that have been stored unused and are in clean condition.

Thank you for your consideration!!
