This rare pair of salt and pepper shakers are believed to be produced by Kralik glass works. As a collector of shakers I have never seen a pair like this and am fortunate to have purchased them. I believe that the pattern is a Feather Design and the glass has both great color as well as iridescence.
The shakers are 3 1/2 inches tall and 2 inches across the base.
I have nothing to compare them to concerning value nor rarity but needless to say they are rare!
