A small sheet of parchment, about an inch in width and 3 inches in length and covered in a glowing film on either face. Upon placing the sheet between a group of objects in a container, and thinking of a certain object from the group you wish to find be it a book, a page in a book, a food item or a tool of sorts, the flag will teleport itself to said object, either fitting itself inside of it or between it and an adjacent object and become outlined with a light only you and select others can see through all objects, granted you aren't blinded. If the object you are looking for is not within the container, the flag fails to move.
