Lenticular cards use a visual trick that gives the image 3D depth and movement. Tilt the card side to side and the image actually appears to shift and animate — it's one of those things that never stops being cool, no matter how many times you've seen it.
These cards are all about the wow factor. They stand out instantly in a stack, and the technology behind them adds a tactile, interactive element that flat cards simply can't deliver. If you pull a lenticular insert, it's the kind of card you'll show off before anything else.
