A pop-up surprise gift box made of thick paper cardboard. Stack the bounce boxes inside, fill the gaps between them with cash or confetti, and close the lid — the boxes spring upward when the lid is lifted, and the faster it is opened, the higher they jump. The folding design sets up and packs down without tools, so it can be reused for birthdays and other celebrations. Measurements: 100 x 100 x 50 mm (3.9 x 3.9 x 2.0 in). Weight: 246 g. Measurements are taken by hand, so allow a 1-2 cm (0.4-0.8 in) deviation. Options: rose, 6 pcs, plus other variants. Each set contains the bounce boxes and 1 gift box; choose a higher bounce-box count if you want a taller, longer pop-up. Colour may look slightly different on screen than in person. Care: paper construction — keep it dry, fill it only with light items such as notes or confetti, and store it folded flat between uses.
