An explosion box is a gift box with a lid and four hinged walls that drop flat the moment the lid is lifted, laying out whatever was folded inside. TBPB prints custom ones with no minimum order, and the price-beat guarantee covers any written quote you bring for the same specs.
How the reveal works
The mechanism is simple once you see it. A base sits under a lid, and the four side walls are scored at the bottom so they can fall outward. While the lid is on, the walls are held upright. Lift the lid and they fall open into a cross shape, exposing the base and whatever sits on it. Layers of cards, folded photos, a message, or a small gift can be arranged on the base and on the inside faces of the walls, so the opening reads like a sequence. The surprise is the product, which is why the interior print matters as much as the outside.
Who buys them and why
You will see them used for birthday and anniversary gifts, proposals, wedding favors and baby announcements. Brands also use them for influencer and press kits, product launch invitations and holiday client gifts, where the opening is part of the content people post online. It is a poor match for fragile or heavy items, because the walls have no structure once open and cannot cushion anything loose. If the item inside needs protection, put it in its own smaller box or tray inside the explosion box.
Board, folds and size
Folding carton paperboard is the natural material. The walls have to fold flat cleanly and then stand up again, so a thinner, well-scored board usually behaves better than a thick one. Heavy board can resist the fold and stop the walls from lying flat. Sizing starts with what goes inside: measure the largest card, photo or gift, then make the base slightly bigger. Because the walls fall outward, remember that the open footprint is far wider than the closed box, and plan the table space or the display shelf accordingly.
Print and finish
The inside faces of the walls are the best printing real estate on this style, so a single repeat pattern, a message, or a photo collage can run on all four. CMYK handles color photography, Pantone matching keeps a brand color consistent, and matte or soft-touch lamination gives a gift-like surface. Foil stamping or spot UV on the lid sets the tone before the reveal. Avoid gloss lamination on the fold lines, since it cracks more easily when the walls open and close repeatedly.
A practical point for event orders: the layers inside are what people remember, so decide early whether you or we handle them. If you supply loose cards or photos, plan how they will be packed so they stay in order during shipping. A short paper band around the closed box can keep the lid from lifting in transit and doubles as a branded detail, which suits shipped gifts well.

Frequently asked questions
What is an explosion box?
It is a gift box with a lid and hinged side walls that fall flat when the lid is removed. The walls reveal cards, photos or small gifts arranged inside, which makes opening it part of the experience.
Is there a minimum order for custom explosion boxes?
No. TBPB has no minimum order, so you can order a single box for a gift or a prototype, or hundreds for an event or a launch. Send your dimensions and artwork, and we draw the dieline for approval.
What can go inside an explosion box?
Cards, folded photos, notes, small flat gifts and light keepsakes are the usual choices. Fragile or heavy items are better in an inner box, since the walls give no support once they fall open. Tell us what you plan to include.
What size should an explosion box be?
Start with the largest card, photo or gift going inside and make the base slightly larger. Remember the open box is much wider than the closed one. Send us the item size and where it will be displayed, and we will check the dieline.
What material is used for explosion boxes?
Folding carton paperboard is the usual choice because the walls need to fold flat and stand up again cleanly. Thinner, well-scored board generally folds better than thick board. We can advise on a weight once we know the size and contents.
Can the inside of the box be printed?
Yes. The inside faces of the walls and the base can be printed, and that is where much of the impact comes from. You can run a pattern, a message or a photo collage in CMYK or matched Pantone colors.
