Vintage Pyrex 4 cup capacity measuring cup with red reverse read lettering. Nice slanted sides shape. Open handle. Numbered on bottom but I cant make it out for the bottom is very cloudy.  
No stovetop ... Microwave OK
Made in USA.
Measures 5 1/4" tall x 7 1/8" across top opening x 9 1/2 inches thick
This measuring cup was really handy as with the open handle I could slip this over another measuring cup for stacking in my small kitchen for easy storage 

CONDITION:  Very USED preowned condition with minor surface scratched and wear on the inside, the bottom is cloudy ...  but no fading to the red on the front of the glass, NO chips or NO cracks.  This item was used but not abused.  Still fully functionable for what it is intended for.
