Chinese Ginger Jar

[ginger]

I came across this item at a yard sale about 5yrs ago. I've never been really sure what it is and the best thing I can guess is it is a chinese ginger jar. It has some kind of potpourri in it, which looks like some kind of mixture of ginger. I'm including pictures of what the jar looks like. I only have one and would like to have another one. Does anyone know what this is and where I could find one? Thanks!
