The explosion (surprise) box springs open the moment the lid is lifted, revealing photos, messages, and tiny gifts on its fold-down walls. It’s the showpiece of handmade gifting for anniversaries, birthdays, and proposals. This template includes the base and lift-off lid — decorate the inner walls with your own photos and journaling.
Note: Single-layer base + lid. The multi-tier nested-layer version is coming in a later update.
How to assemble
- Cut — Load 65–110 lb cardstock and cut the file. Solid black lines are the cut paths.
- Score — Run the dashed lines as score/fold lines (the separate SCORE layer). Scoring makes crisp folds.
- Fold — Fold every scored line, folding away from the scored side for sharp edges.
- Glue — The base walls fold up and are held by the lid (no glue). Glue only the lid’s tapered tabs. Let it set before filling.
Cardstock tip: Use 65–110 lb (176–300 gsm) cardstock. 65 lb folds easily for small boxes; 80–110 lb gives larger boxes and lids more structure. Always score before folding.
