These are the best note cards ever. Whether plain lined or grid printed they accept either graphite or ink. I bet they even would accept crayon or colored pencil although those are not accessible for me. The brilliant white paper is a little stiffer than plain paper and would probably remain so even after using an eraser on them. I highly recommend them for any paper or card stock use. They are not an acceptable substitute for ZIGZAG
The price and quality of the ten reams of paper is a great buy. I use a lot of paper for my own personal needs and for preparing lessons for my 4th grade granddaughter and my church class. I am so thankful for the kind young man that carried the heavy box of paper out to my car on a rainy day!
