This is a lot of 4 vintage milk glass and green glass bird cage seed feeders.  One of the white ones is marked Made in Japan, the other three are unmarked.  The one white one with the floral design is in excellent condition and even has a bit of opalescence to the clip portion of the seed cup.  There are a few straw marks in the mold on the front that are original to the piece and are not cracks.  The one Made in Japan is in excellent condition with no cracks and the only chip is a very tiny one on the clip portion which won't affect use at all.  The third white one is unmarked and could only be used for seed as there is a teeny little pinhole in the bottom corner. Other than that it is perfect. This one does not have a back clip so would need a spring ring to attach to the cage.  The dark green one is totally usable; however, it does have a chip on the top of the opening that extends into a hairline crack on the front (doesn't affect use).  There is also a chip on the clip that I don't think will affect use but I can't swear since I don't have a bird cage to check it. Sizes range from 3" to 3-1/4" high.
