Thank You Coloring Note Cards with Envelopes (6 Pack)
Product Review (submitted on October 5, 2017):
These have 3 nice coloring patterns but the packaging states these are "premium heavyweight cards". They are by no means"heavyweight" in the card making world, maybe in the copy paper world. There is no weight listed but my guess is 30-40 lb. Any markers used to color will bleed through. Colored pencils will be the only option if you don't want the blred through.
