A multi-panel fold-out device made from a blank includes at least first, second, and third panels which are joined together in sequence, and formed by separation lines between the first, second, and third panels. The first and second panels each have an internal panel portion including a score line adjacent to an edge of the panel. Each internal panel portion is releasably secured to its panel such that the internal panel portion can be pivoted around its score line relative to its panel. The first panel is foldable over, along the first separation line, to secure the first panel to the second panel. The first and second panels are foldable under, along the second separation line, to secure the first and second panels to the third panel. The first and second internal panel portions are of different sizes so that these panels can be folded out in sequence.
