Prym Ergonomics 32" Circular Set, Size US 2, 4 & 6 Knitting Needles, Assorted 3 Count

What are the sizes in mm of these needles?

Can any knitters tell me what the cords and joins are like on these needles? are the cords floppy? compare to hiya hiya and chiaogoo? thanks!

Does Prym make any circular knitting needles with short tips and short cables?

Why is there no Size 9 available?
