Glass Sengbusch Emeralite Inkwell Thing

Green glass about 9x7x1. First photo includes tictacs for scale.
Hole about 2 inches in diameter in the middle, flat on one side with the decorative curves on the other. Some sort of inkwell accessory made my Sengbusch for Emeralite.

Thanks for the help identifying it.

Update: I found a second piece. It isn't labeled, but it fits perfectly. The last picture shows a clear glass teacup-looking thing. It also has a hole in the bottom, and fits in the center of the larger green glass.
