Pyrex vintage Butterprint 443, 442, 441

Turquoise Blue Butterprint 443, 442, and 441. Each of these bowls do have a small chip on them. The 443 being the worst one, shown with the pen in the pics. The 442 chip is on the one corner of the spout and barely noticeable. The 441 chip is at the top of the brown mark that is in the glass. I have no idea how the brown mark was created. It appears to have been burnt into the glass??? All 3 appear to have some type of dishwasher damage. The 442 is not as noticeable because it still has some shine to it. The 441 print is dull and fading. The 443 print is dull, but mostly ok.
These would make great workhorses if you want to use your vintage Pyrex.
Also would be a good beginner set for the person just getting started with collecting.
