Pyrex 501-B Refrigerator Dishes Small Fridgie Set 4 White‎ Tan

Vintage Pyrex Set of 4 Rectangular Side Dish Refrigerator Fridgie Dishes Corning NY USA Small Color- Tan/ Light Brown/Woodland Brown Size- Height 2 1/2” 4.25x 3.25” Each are marked 501-B # 16,18,27,33 350 ml (about 1 1/2 cups) * the last photo show 1 cup of water with extra room As you can see,some have a tiny extra paint drops on the bottom. I held them all to the light to try any find any imperfections but the close up photos changed the color darker. They are very clean,no chips or cracks and no big scratches- nothing major. Super shiny finish with very few signs of use. I inherited this set from my grandmother. They were stored in the kitchen cabinet on the very top shelf without lids. From my research, they are refrigerator dishes but maybe they’re just side dishes???? I’m sure they were not used for many years because I needed to climb a ladder to reach this spot and she definitely wasn’t the type to use a ladder. 😉 This is a great find and nice that all four match. I’m not an expert, it’s just my research.
