vintage 3.5" clear glass Flower Frog with 11 stem holes for floral arrangements

vintage flower frog
condition: good

11 hole flower frog
clear, colorless glass
diameter: 3.5"
height: 1"
has three small disc feet on bottom - instead of rounded nubs for "feet" it looks like three flattened discs that rise slightly above the surface - I'm sure that explanation is clear as mud!

good condition
small crack on rim (see last photo) - it honestly seems like a manufacturer's defect rather than a crack - edges are smooth - hard to tell
