You'll never guess what it is
The author of the video shows us a small object that fits in the palm of your hand. Its dimensions resemble a regular card, except that it is thicker. At first, you can't understand what it is, but then the guy shows everything in more detail... You will definitely be surprised when you understand what this thing is.
And it turns out that this is a firearm. Yes, it is small in caliber, but it is quite possible to injure a person if you need to defend yourself. You just need to load the cartridge, unfold the "box" and pull the trigger that appears. In addition, there is a special compartment where additional cartridges are stored.
