This is a common Pyrex custard cup that you’ll find in many thrift stores and is actually a great size for actual occasional usage around the house. They are pretty inexpensive and durable so you don’t have to worry so much about breakage. The 10 ounce Scalloped Edge (also called Ruffled Edge, Riffled Edge, or Wavy Edge) Custard Cups were said to have been introduced in the 50s. There are numerous varieties of this cup, though they all have the familiar wavy edge.
The older ones were sold in sets of 6 and many exist in original packaging (yellow cardboard trapezoid looking cutout) although I don’t believe the scalloped edge sets came with the familiar wire cooking rack that is associated with these cups. I’ve seen variations in glass thickness for the cups with the same number, and the capacity written as either “10 oz.” or “300 ml”. Although we took the metric numbered ones to be newer, the glass on the 10 oz. ones feels thicker and more sturdy (this which seems to be contrary to what I’ve seen a few people say online).
