what are the print runs on refractors?
 

Does anyone know what the print runs on bowman refractors are? I know some come numbered but most refractors don't. Is the print run shorter than a plain bowman card or about the same?

Depends on the year. Rarer than base/paper cards, but more common than any colored or xfractor card. Usually you can figure out the print run by comparing the odd on the wrapper.
If the odds say something like:
Refractor 1:2 packs
Gold Refractor (/50) 1:200 packs

There would have been 100x more refractors than golds, so 5,000.

Well there are so many of them that I guess they're all numbered the same? You have the ice refractors offered in paper and then you have blue,orange and green wave refractors,purple refractors,shimmer refractors and just regular refractors. Lets just take 2014 bowman chrome for example. I have at least 5 Carlos Correa refractors and 1 regular chrome card. Only one of them is numbered. The other 4 are bowman paper ice,blue wave,89 bowman is back and plain refractor. I have no clue what the print run is so it makes it harder to determine what's worth keeping when space gets tight.

Thanks for that! Wish I would of known about that sight a long time ago.
