I have not seen one of these before with such a lack of color in it. Here is a pic of it beside a glass mug to try to capture its clarity. I have pulled ones I would call off-clear - but cannot find a trace of color in this (and two out of 5 others I got the other day). The clearest one I have (besides this and two others I got with it) now look very "off clear" when sitting side by side. I do not see a 'clear' listing in the book. Has anyone else ever seen one? I did not see it in the book.
