This is a multi-storage shaker. Now you can put more than 1 ingrediant in this shaker. To assamble it, push the lid (the one with dotted and a big hole in it) into the main container. When you do not wish to use it, screw the cover on (the one with one hole). There are two files, one with two sections and one with four.
You can change the size of this shaker depending on how much of each ingrediant you would like.
