I have been looking at my german swirls, I think that they are, that do not have a lot of surface damage, but there is so many bubbles inside, with little dots of color inside on the lines, and what looks like long digs but they are on the inside as far as I can tell. Were thest made poorly? I know the ponstils on each end are present, but it seems like they are crude. Any ideas. Thanks Barb
