When one refers to a "fold-out" object, they generally mean something that can be easily opened up and displayed. However, there are several other terms that can be used interchangeably to describe such items. For instance, "pop-up" is commonly used to refer to 3D objects that are designed to spring up and stand out when opened up. Similarly, "flip-out" refers to something that can be flipped open to reveal its contents. "Expandable" is another term that can be used to describe objects that can be easily extended or stretched out, whereas "unfoldable" refers to something that can be unfolded. Lastly, "unfurl" is used to describe something that can be rolled or spread out to full length.
