## Description

This black cardstock has a unique and intense shade of black like no other. It's the new black refined for performance. An innovative composition of pulp processed without carbon black, prevents oxidation and is extremely light-fast. Uncoated surface takes white ink and mixed media color applications like no other. Why do black when you can do Ultra Black.

Review: This is the purest black paper I’ve found and the thickness is great for what I need it for, die cuts. Will purchase again. Very happy with sellers fast shipping.
Review: This is a nice deep black paper and scores, stamps, and die cuts very well. Only area where it performed less well was in heat embossing. Black paper in general is more prone to static but you can usually overcome this by drying the paper out first with your heat tool and using an anti-static powder bag before stamping and embossing. In this case I was unable to get a clean emboss without the powder sticking to the paper. Used a fine paint brush to get the powder off the card stock before embossing my stamped image but never able to get a clean panel. So, four stars from me.
