Frequently Asked Questions
How long does a pop up card last?
Decades, if kept dry and out of direct sunlight. The paper used in quality pop up cards is the same acid-free stock as fine art prints, which is why so many become keepsakes.
Do 3D pop up cards cost more than regular cards?
Yes, typically $12-$39 versus $3-$8 for a flat card, because each one is cut, folded and assembled by hand in multiple layers. In return you get a keepsake most people display for months - or years - instead of tossing it after opening.
