Somehow my 25-year-old Pyrex 1-cup measuring cup disappeared so I needed a replacement. In stores, the only Pyrex is a new shape, and I wanted the old shape. Another brand was on the shelf, but that cup was so small! There is only room to measure the liquid, not mix it or add another ingredient like in the Pyrex cup. I went online to see if the old shape was still available and I found this website. The prices were fabulous and service was great!
