Mirror Box Internal Mirrors

Mirror boxes generally come in 2 forms: mirrors on the inside, and mirrors on the outside. On rare occasion, and by request, they can be combined, mirrors on both inside as well as outside. 

Mirror boxes tend to have opposite functions depending on where the mirrors are. Mirror boxes with the mirrors on the inside are generally made to reflect back unto what is contained within. Meaning that if a target was placed inside then everything they emanate and project is reflected back unto them, in a spiritual metaphysical sense. These can, and are often used to, trap and contain, curse (by locking a subject inside with the curse), and in various other creative ways. These also tend to greatly increase the effects of what is done inside. We use these often in our casting services and workings. 

Mirror boxes with the mirrors on the inside are worked while your visage is obscured, and it is important to not get your reflection in any of the mirrors. Once the mirrors "see" a person then they know who it is casting with them, and this is not advised (if the mirrors have seen you then it is advised to discard them entirely. )

Mirror boxes with the mirrors on the outside are generally protective, as in they reflect away all the spiritual metaphysical things that are sent and projected at it. They are also used to obscure and camouflage what is inside in a way that divination and remote viewing is unable to easily perceive. 

Double mirror boxes use both of the techniques mentioned.
