BIC pens are designed to be simple, reliable, and high-quality writing instruments. However, you may need to open and disassemble a BIC pen for various reasons, such as replacing the ink cartridge or modifying it for pen spinning. While BIC pens are not designed to be refilled, it is possible to disassemble them using various tools and techniques.

What You'll Learn
Twist the top off
To open a plastic BIC pen, you can try twisting the top off. Here is a step-by-step guide:
- First, identify the different parts of the pen: the cap, the barrel, the ink cartridge, and any other components like a metal ring or button.
- Pinch the front part of the pen, which is usually the cap or a coloured section, and grip the barrel firmly with your other hand.
- Twist the cap or front section back and forth, applying a gentle force to loosen it. You may feel some resistance, but with persistent twisting, you should be able to unscrew the top.
- If the pen has a metal ring or a similar dividing line, use it as a guide for where to twist and apply force.
- Once the top starts to loosen, you can carefully pull it off, revealing the ink cartridge.
- To reassemble the pen, simply reverse the process. Place the top half of the ink refill back into the pen, and push the two halves of the pen together firmly.
It is important to note that some BIC pens may not have a twist-off mechanism, and you might need to pull the pen apart, as described in other sources. Additionally, some BIC pens have a back plug that can be removed using pliers or other tools, but this is not part of the standard disassembly process.

Remove the ink cartridge
Removing the ink cartridge from a BIC pen is a simple process, but it does require a bit of care to ensure the pen remains intact. Firstly, you will need a pair of pliers to help you grip the pen securely without slipping and breaking the plastic.
To begin, locate the ink cartridge inside the pen. You will need to pinch the blue part of the cartridge with one hand, and the ink cartridge itself with your other hand. Gently but firmly, push the ink cartridge further into the pen, with the aim of pushing the writing tip out of the blue part. This step may require a bit of force, but be careful not to crack the plastic.
Once the tip is dislodged, use your pliers to gently squeeze the pen near the blue part. This will help loosen the cartridge. Again, be mindful not to squeeze too hard, as you don't want to break the pen plastic. After this step, the cartridge should be easy to take out.
Now that the ink cartridge is removed, you can store it safely if you plan to reuse it. It is best to set it down in a safe, easy-to-clean spot, such as on a table or a clean surface. If you need to store it for a short period, you can seal the cartridge with tape and keep it in an airtight container or a small ziplock bag. This will prevent it from drying out for a day or two.

Unscrew the bottom
To open a plastic BIC pen by unscrewing the bottom, you will first need to remove the pen cap and any other attachments such as a clip. Then, carefully twist the top part of the pen anti-clockwise and pull it off from the bottom barrel.
Inside the bottom barrel, you will find the ink cartridge. You can remove this by gently pulling it out with your hands. Be cautious not to damage the cartridge or any other components during this process. If you are unable to remove the cartridge with your hands, wrap the pen in a thick sheet of fabric and use pliers to pull it out.
Once the ink cartridge is out, you will be able to see the spring and any other remaining pieces inside the bottom barrel. To fully disassemble the pen, simply unscrew the bottom of the pen to release these pieces.
It is important to note that some BIC pens may have their back plugs glued on, making it difficult to open. In such cases, you may need to use tools like pliers or a giant needle to carefully pry the back plug out without damaging the barrel.

Replace the spring
To replace the spring in a plastic BIC pen, you will first need to open the pen. This can be done by firmly grasping each end of the pen in each hand and using the metal ring as a dividing line. Then, pull the two ends of the pen apart.
Once the pen is open, you will see the spring on the bottom of the ink insert. To replace the spring, first prepare a new spring of similar size and shape. You can find inexpensive ballpoint refills at most office supply stores, or you can salvage them from other ballpoint pens. Ensure that the new spring has a pinched section to keep it in place. If it does not, you can carefully create one using pliers, being careful not to choke the flow of ink or cause leakage.
Next, transfer the spring from the old ballpoint insert to the new one. Place the new insert with the spring into the bottom half of the pen. Check if the pen tip comes out smoothly when pressure is applied. If it does, you can reassemble the pen. Screw the two halves of the pen back together, being careful to align all the parts correctly, especially the spring.
If you are having trouble opening the pen, you can try using a pair of pliers to gently squeeze the back of the plug. You should hear the sound of cracking as the superglue comes undone. Then, carefully remove the back plug with the pliers. Alternatively, you can use a chopstick or a giant needle to pry the plug open.

Put the pen back together
Once you have opened your plastic BIC pen, you can put it back together by following these steps:
Firstly, ensure you have all the parts of the pen. You should have the bottom half of the pen, a metal ring band (which may be fused to the bottom half), a ballpoint refill insert, a spring on the bottom of the ink insert, a plastic cap on the top of the ink insert, and the top half of the pen.
Next, place the spring on the ink tube. Then, insert the ink tube (with the spring still on) into the large pen tube. The unnamed plastic part should be nestled into the end of the pen tube before inserting the ink tube.
Finally, screw the two halves of the pen together, and test if the pen works. If the pen is not writing, try dipping the tip in acetone or another solvent, or scribbling on a rubber surface to get the ball rolling.

First, remove the cap and any additional attachments such as a clip. Then, carefully unscrew the top part of the pen from the bottom barrel. You can use pliers to help you do this, but be careful not to squeeze too hard, or the plastic will break.
Once you've separated the two halves of the pen, you should see the ink cartridge inside. Be careful not to damage the cartridge or any other components during disassembly. Gently pull out the cartridge.
Try wrapping a thick sheet of fabric around the pen and use pliers to pull out the tip. You could also try prying the cap out with your fingernails or cutting the barrel shorter.
Put the twist cap back on the top half of the ink refill. Push the two halves of the pen back together using the same firm two-grip method you used to open the pen. If there's a small gap, twist the pen to extend the tip and then push the two halves together to close the gap.
