Cased Glass Bowls - Unsigned - Please help identify maker & country

Hello, I bought a collection of glass bowls and vases. 2 were Holmegaard and initials for Per Lutken. I should appreciate help with identifying the blues and purple bowls please.

This purple one has a smooth base





Many thanks. I will send photographs of the blue ones in a separate post.

Clara, I'm sorry to say I see these everywhere, they must be modern.
Not exactly sure where from.

The blue one, difficult without seeing it, but it's probably the ones we used to see in 2005 with Ikea labels, they come in in different colours. http://glassgallery.yobunny.org.uk/albums/userpics/10011/Picture%20525.jpg

Purple one i have seen before, Magnor maybe?
