Add an extra special surprise to the inside of any card with the Pop-Up Base Dies! Each die is scored so they can be attached to both sides of the card, meeting in the middle to form a 90° angle. Once you've attached the bases you can take any number of stamps and dies in your crafty stash and build your card. Some of our favorites include the Downtown Stacks Bundle, Make a Wish Bundle, and Birthday Scoops Bundle! 3 pieces.
