Blue glasses - Nuutajarvi?

Hello,

I am nursing a budding obsession with Scandinavian glass from the mid-century, and stumbled across your community while searching for information on these blue glasses that I recently purchased. They were unmarked but the seller said they reminded her of glasses designed by Saara Hopea or Kaj Franck for Nuutajarvi. They are 7" tall by 2.5" at rim slightly tapered (1 7/8" at bottom).

Does anyone know who made these and whether they come in other colors? They are sooo nice and make a glass of water taste 10x better! :)

Cheers,
CC
