I don't know who made this nor its exact age. I think it might be from the Depression era -- if so, it is antique. It think it is either a small pin tray or a master open salt. It is 2 7/8 inches wide and 3/4 inch tall and weighs 3.2 ounces. The glass is frosted, and light green, with possibly a yellow tint. It is uranium glass and glows nicely in black light.  The outside shape is octagon, and the inside is round. The bottom has concentric octagon shapes/ridges.

It has a tiny chip 2 mm wide on the inner edge of the top, and a couple of nicks -- one is 1 mm wide and the other is too small to measure. On the outer edge there are a couple of nicks 1 mm wide and 4-5 that are too small to measure. (The tiny 2 mm chip is really the only one that's visible, because it is shiny there instead of satin.)

(My black light photo was taken under a 395 nm UV light -- so it only shows uranium glow, not the fake glow of manganese.)

This will be shipped by my choice of either UPS Ground Saver or USPS Ground Advantage rate (except for International). Local delivery is always available for free to a mutually agreed upon meeting place. I will combine shipping if you purchase more than one small item from me.

I am happy to answer your questions about this piece.
