LEGO Unboxing Guide: Check Seals, Bags and Minifigures
Every new release brings that itch to tear the box open. But plenty of builders rip the seals off, get halfway through the build, and only then discover a missing part, an off-centre minifigure print, or — worse — that they bought a returned set someone already picked through. A proper inspection takes about ten extra minutes and saves hours of after-sales hassle. Here is the full unboxing and verification workflow, start to finish.
Before Opening: Inspect the Outer Box and Seals
Don't grab the scissors the moment your parcel arrives. First check the outer carton for crushing, water stains, or signs that it was sealed twice. On a genuinely factory-sealed box, the seals on all six faces should be complete and flush, with no repeated creasing along the folds and edges. If you spot leftover adhesive under the edge of a seal, or a lid that has been pressed flat again, be suspicious — that is likely a return or a display sample that has already been opened. The unboxing experience suffers, and the contents are very likely incomplete.
One more thing worth doing: authentic boxes have a batch code and country-of-origin information printed on the base. Photograph it for your records. Collectors in particular should keep that shot — it comes in handy for authenticity checks, part replacement requests, and resale later on.
After Opening: Count the Bags and Check the Instructions
Once the box is open, take everything out piece by piece and sort it into groups: instructions, sticker sheet, numbered bags, and minifigure bags. On a standard set, the bags carry printed number codes that map strictly to the page order of the instructions. Check two things carefully. First, whether the bag numbers run continuously from 1 to the last number, with no gaps or skipped numbers. Second, whether the quantity of each bag matches the bag inventory printed on the first page of the instructions.
If one bag feels noticeably light, don't open it yet — weigh it and compare. Adjacent bags in the same set normally differ very little in weight, so a clear discrepancy deserves a closer look. This is the step people skip most often, and it is the most important part of any unboxing inspection.
Verify the Minifigures: The Most Overlooked Check
Minifigures are the soul of a set, and they are also where missing parts and defects show up most often. Open the minifigure bags and immediately work through the minifigure list at the end of the instructions, checking count, skin tone, facial expression, and accessories (helmet, weapon, hairpiece) one by one. Common problems include a missing figure, a face print that sits off-centre, and arm joints that are too loose.
A practical trick: assemble every minifigure first, then check that the limbs move smoothly and that the printed details are centred. Some production batches show slight colour variation on legs, which is acceptable if it doesn't affect play. But if one leg is clearly a different colour from the other, go straight to after-sales support.
What to Do If a Part Is Missing
If your count really does turn up a missing part, don't panic. Many "missing" parts are actually stuck in a flap of the box or inside the sticker bag — search thoroughly before you conclude anything. Once you've confirmed it's gone, use the missing-parts portal on the official LEGO website to submit a replacement request: enter the set number, the part number, and the quantity, and the replacement ships free of charge. The part number you enter is the digit string from the parts list in the instructions — which is exactly why photographing that list during unboxing pays off later.
While you wait for the replacement, build the sections that don't depend on the missing part and leave that spot until last. Don't force a substitute part into place just to finish.
Final Thoughts
The real pleasure of unboxing is watching a pile of parts turn into a finished model, and a disciplined inspection carries that pleasure all the way to the last brick. Get through the outer packaging, the bag count, the minifigures, and the missing-part check, and you can enjoy the build itself with a clear head. If you want to study a set's structure and parts list before you even open the box, visit BrickPlans (https://brickplan.cn), where building instructions, MOC designs, and parts cross-reference material are updated continuously — so every unboxing starts on solid ground.
