I found this on an internet search:
•Blended by expert acrylic paint formulators Acrylicos Vallejo to Micro-Mark specifications
•Color matched to PollyScale paint samples. Labeled with PollyScale color names for easy cross-reference.
As far as price, it's 2 ounces, or 59 ml, so it's the equivalent of about 3.5 Vallejo bottles. But it doesn't say it's rebranded Vallejo paint, which means it's not likely the same, but for people needing a replacement for PollyScale, it might be just what you need.
