I had worn my Pyrex measuring cups out!  The cups themselves were good, but the red measurement lines and numbers were invisible - that shows how long I have used them.  Glad to find all three sizes available in a single purchase.  They arrived in perfect condition, having been packed securely, and I retired my worn cups and am happily using the new ones where I can clearly see the measurements.  These will probably last as long as the retired ones!
Great purchase
