Searching for something else I came upon this information for a company called AriaMotion, Dalian, China (and another of their brands called Casamotion).
Since there is little information available at the moment when trying to understand who made what, either if it is Chinese glass or glass branded under a wholesaler, then I thought for future info this was interesting.
I copied the info from their website in case the link becomes inactive in future - I hope this is ok. One of the pieces I was looking at is sold in multiples of a minimum of 300 order and they say they can produce 99,999 of that item per year!
'Ariamotion,establised in 2002,is one of the largest companies specialized in decorative handmade glassware in China.We have 2 wholly-owned factories in Dalian China mainland with employees more than 500,and have established long term cooperation with twenty more glassware factories in north China.
