2014 Bowman Chrome Football Forum

How can you tell the difference between the Refractors from the regaulr cards for this set?  For previous issued sets the card had Refractor on the back.  The set 2006 Bowman Chrome Football had this distinction.  For the 2014 set I don't see Refractor on any of the scans posted.

Thanks for any help provided.

Hold them in the light and told them around.  The refractors will have a rainbow effect to them.

Thank you for the tip.  It would have been easier if Refractor was written on the back.
