Generally speaking, the Box is an extremely big (im)possible, (un)imaginable, (non)theoretical, (un/meta/pata)physical, or use(ful/less) set. If you can think of something, it's inside the Box. If you can't think of something, it's inside the Box. Anything that is even declared without thought, subconsciously, is in the Box. The Box is in the Box. Logic and all permutations of logic are inside the Box as well, which simultaneously allows it to contain itself as well as deny characters or -verses any sort of excuse by saying "it doesn't conform to the Box's rules". They aren't the Box's rules, they just happen to be in the Box too. The Box also follows this logic and contains itself an infinite amount of times.The Box also follows all types of physical realm using all properties, including metaphysical realm and pataphysical realm. It is impossible to define anything outside the Box, because by mentioning a fact about something, you have placed it in the Box. The box has the Le Jorino Area inside of it. So, it is not really a verse, because it contains the Le Jorino Area. This is a contradiction, so the box should not be classified as a verse.
The Box contains itself, naturally, as The Box is a container that exists, meaning it has an endless loop of self-containment. This means when you escape a Box, there will be another Box directly after it.
Thus, it is impossible to escape The Box, since no matter how far you go out, there will always be another Box.
