Good morning and thank y'all for having me along. I have had this bottle for over 15 years and still can't find one like it. It has a flat concaved bottom that is the size of a nickel. It expands up just over an inch where the second part builds to the lip. There is a seam on one side that starts at the bottom and then disappears. Another seam on the other side begins at the bottom of the top section and ends at the lip which has a seam running around it. It is clear glass with a turquoise fluid inside (Ink?). The top section has an extra swirl blob of glass just below the lip and it has small bubbles here and there. It is thick and heavy. Just under 3 inches tall and 3 inches in diameter at its widest. Anyone? Thanx!! Rob=Bob
