Core'dinations Color Core Vintage Cardstock ATCs - Reminisce. Core'dinations Color Core Cardstock is pre-sanded cardstock in warm deep colors for vintage look. The inner core of the paper coordinates with the outer canvas texture color, so when you tear it, antique it or sand it more, the inner shade shows up even more. I love this cardstock since it is like a 2 for 1 paper. This package contains all 30 of the shades available in the Core-dinations Vintage Collection - Reminisce. The cardstock is premium 80 lb. canvas texture paper that has been cut to 2 1/2 in. X 3 1/2 in Artist Trading Cards. You will receive a package of 30 cards as shown in the photo. PLEASE NOTE: THERE ARE SO MANY DIFFERENT KINDS OF CORE'DINATING CARDSTOCK. THIS HAS A LIGHTER COORDINATING COLOR WITH AN OUTER CANVAS TEXTURE PAPER.
