I have a large jadite collection and I am slowly offering a few of my pieces. I love the dark jadite, too bad they didn't make very much of it. This shaker is in good condition, it has the usual straw marks and one, very small chip in the bottom, still a great looking piece to use or display. The lid doesn't want to stay on, but it will with a bit of persuasion.
There is just a few specks of black paint left, it is a salt shaker, the lettering has worn off.
It is 4 & 3/4" tall with the lid and 2 & 1/4" square. I will be offering the same shaker in the light jadite, too. Looks wonderful with your Fire King and Jeannette!
