Charming bowl with green decorative accents. Perfect for serving or display. this has clearly been used. no chips or cracks. as you can see there is wear and some cosmetic imperfections along the outside. im not sure what caused the markings. maybe just storage and use over time? looks like pencil or something but its not. please SEE ALL PHOTOS Pale yellow bowls with a simple green floral pattern on each side. Pyrex's Shenandoah pattern, produced from 1981 to 1986 is one of the last patterns released before discontinuing production of opal Pyrex.
