How to Open Lego Box

Lego is one of the most popular toys globally and has been around for decades. The Danish company is known for its colorful interlocking blocks, which can be used to build just about anything imaginable. Whether you’re a child or an adult, there’s no denying that Legos are fun to play with. But one of the most frustrating things about them is trying to open the box. If you’ve ever struggled with getting a Lego box open, you know how frustrating it can be.

What Is Lego?

Lego is a construction toy consisting of interlocking plastic bricks and an accompanying array of gears, minifigures, and other parts. Lego is manufactured by The Lego Group, a privately held company based in Billund, Denmark.

The company’s flagship product, Lego, consists of colorful interlocking plastic bricks accompanying an array of gears, figurines called minifigures, and various other parts. Lego pieces can be assembled and connected in many ways to construct objects, including vehicles, buildings, and working robots. Anything constructed can then be taken apart again, and the pieces used to make other objects.

The Lego Group began manufacturing the interlocking toy bricks in the mid-19th century. However, the company has come a long way since its humble beginnings, and it now operates factories worldwide.

How Are Lego Boxes Sealed?

Sealing a Lego box is a two-step process that begins with gluing the edges of the box together. Once the edges are glued, a machine locks the lid with plastic tabs. This sealing method is strong and tamper-resistant, ideal for protecting Legos during shipping and storage.

However, it can also be challenging to open, especially for small children. As a result, many parents choose to carefully remove the tabs before giving their child a Lego set. By taking this extra step, they can help to ensure that their child has a fun and safe experience with their new toys.

A Step by Step Guide on How to Open Lego Box

Step 1. Determine What Kind of Lego You Need

There are many types of Lego. The most popular type is the “mini figure,” a small plastic figurine that stands about 2 inches tall and comes in many different designs. Other kinds of Lego include “bricks and plates,” which are larger building blocks, “Duplo,” which are larger blocks for younger children, and “technics,” which are specialized pieces used to build working models.

Step 2. Find the Right Box

Once you know what type of Lego you need, you need to find the correct box. Lego boxes come in different sizes and shapes depending on the kind of Lego they contain. For example, mini figure boxes are rectangular and have a picture of the characters on the front, while technic boxes are square and have a picture of the model on the front.

Step 3. Finding the Instructions

Instructions for assembling Lego models can be found in the instruction booklet with the set. This booklet can usually be found taped to the inside of the box lid. If you can’t find the instructions, you can also look online at the Lego website or a third-party site like Brick Instructions.

Step 4. Opening the Box

Now that you have the instructions, it’s time to open up the box. Start by opening the lid of the box. Once the lid is open, you should see a plastic bag with all the Lego pieces inside. Cut open the plastic bag and empty the contents onto a flat surface.

Step 5. Sorting the Pieces

The next step is to sort the pieces by type. This will make it easier to find the pieces you need when you’re ready to start building. First, separate all of the different pieces (bricks, plates, technic pieces, etc). Then, within each category, sort the pieces by color.

Step 6. Start Building!

Now that your pieces are sorted, you’re ready to start building! Refer to the instructions that came with your set to see how the pieces fit together. If you get stuck, there are plenty of online resources that can help, like Brick Instructions or The Lego Movie Database. These steps will help in how to open lego box. Have fun and be creative!

Tips and Warnings


  • If you’re having trouble getting the lid off, try turning the box upside down and gently shaking it. The lid should come loose.
  • If the lid is still stubborn, try running a butter knife or other blunt object along the seam between the lid and the box. This should loosen the adhesive enough to allow the lid to be removed.
  • Once you’ve opened the box, be careful of the sharp edges on the plastic bags inside. These can cut skin quickly, so handle them with caution.


  • Do not use sharp objects to pry open the box, as this can damage the contents inside.
  • Be careful of the sharp edges on the plastic bags once you’ve opened the box. These can easily cut skin, so handle them with caution.

Lego boxes are a notorious source of frustration for parents and children alike. The lid is often tightly sealed, making it challenging to get off. However, you can use a few tricks to make the process easier. With a little patience and elbow grease, you should be able to get that pesky lid off in no time.

How Can You Tell if a Lego Set Has Been Opened?

If you’re considering purchasing a used Lego set, you may want to check if it has opened before. Here are a few ways to tell:

  • Check the condition of the box. If it looks like it has been opened and resealed, it probably has.
  • Look for signs of wear on the Lego pieces themselves. If they appear to have been played with, the set has been opened.
  • Ask the seller directly if they know if the set has been opened. They should be able to tell you if they remember opening it themselves or not.

How Can You Tell if a Lego Box Is Sealed?

If you are not the original owner of the Lego box, it can be difficult to tell if it has been opened before. However, there are a few ways that you can check:

  • Check the level of wear and tear on the box. If it looks like it has been opened and resealed, it probably has.
  • Look for any ripped or missing pieces of tape on the box. This is a sure sign that someone has already opened it.
  • Try to open the box yourself. If it seems sealed shut, it probably is.

Do Lego Sets Lose Value if Opened?

It’s a common question among Lego collectors: will it lose value if I open my Lego set? The answer is maybe. While some factors may lead to a decreased resale value, others could increase the value of the set.

When it comes to unopened Lego sets, the general rule is that they will hold or even increase in value over time. This is especially true for older or retired sets that Lego is no longer producing. However, some newer sets may not appreciate as much, mainly if they are part of an ongoing series or theme.

One factor that could decrease the value of an opened Lego set is if all of the pieces’ bags are opened and mixed. This makes it difficult for the buyer to know if all of the details are accounted for, leading to a lower price. In addition, if the instructions and box are not included, this will also likely lower the value.

On the other hand, some factors could increase the value of an opened Lego set. For example, suppose a set is particularly difficult or time-consuming to build. In that case, the fact that it has already been assembled may appeal to buyers (especially if they don’t have the patience or skills to do it themselves!). In addition, specific Minifigures or rare pieces no longer in production may be more valuable when included in an opened set.

Opened Lego Set

So, while there is no definitive answer as to whether or not an opened Lego set will lose value, it depends on several factors. Ultimately, if you are thinking about selling your Lego set, it’s good to do some research first to see what similar sets have sold for in the past. This will give you a better idea of what to expect in terms of price.


So there you have it – the six simple steps on how to open lego box. By following these tips, you will be able to open your Lego boxes quickly and easily, but you’ll also avoid damaging them in the process. Have fun building!
