The designation Quran holder is interesting because it has not so much to do with the sliding lid...although this is in fact true ...and is an excellent bit of logical detective work...but that it is the decoration on the box and its shape which signifies its use....Artwork has to be geometrical as this was the form of art linked to the religious form...There is no way a box of this definition could be used as a bullet container...What I find odd is that these two items are part of a set...perhaps the item that looks like a powder flask is only a decorative item?...or talismanic...
