"'Unlike Felix had expected that his parachute would be returned in the same state, they already knew that his parachute was a goner the moment Saltz Master died.""That's because objects transported to the shadow realm would be subjected to the laws of that realm.""They weren't friendly in slightest to anything that wasn't a shadow or had tremendous affinity to the element.'          -Chapter 544"

It is also known that Unigin have the purpose of guarding and moderating the universe's Laws. It is assumed that they are extremely limited in using their powers.

The Difference Between Laws and Elements
No matter what method used, it is almost impossible to recognize the difference between material made out of laws and material made out of elemental energy, Both of them have the same structure of molecules and they react the same to other materials. But in reality, there is a massive difference between laws and elements. The moment the elemental energy gets cut off, the created material, ability, or whatever you imagined will disappear shortly after The only thing left behind is the aftermath of its existence. In a sense, materials made out of laws are real but materials that are made out of elemental energies are perfect copies.
