How to open a Gillette razor blades refills box (magnet needed)

Since there wasn't any video of how to open these boxes, I decided to make one. There are 2 ways to open it. For the first one you will be needing only a magnet, and for the second one you will need a hacksaw / cutting pliers or even a knife would do. For the first way, all you need to do is place the magnet on top of the cylinder and then press on that little plastic button on the other side. For the alternative way, you will need to cut that plastic cylinder and pull of that metal part out. You won't be needing to brake these boxes again and you could keep them in an untouched condition.
