NORITAKE Japan Glass Vases

This trio of small vases are not marked Noritake but I have seen photos of at least one of these with the gold Noritake sticker, so I'm going with it.

I don't think Noritake made their own glass, more likely it was outsourced and marketed under their name. Who made it, I have no idea.
I don't know the age of these vases although the one I saw with a sticker made me think pre 1990s because of the sticker used. They show a bit of wear on the bases but a date would be a guess.

Blown flask shapes in clear glass with a coloured glass overlay on the base.
The walls of the vases are quite thick and they are heavy for their size.

They are quite small, ranging from 7cm (2.5in) to 13cm (5in), and I think they will look gorgeous when I can get some violets for them.

Interestingly these pick up the colours of my Matsuura vase well!

UPDATE
I have confirmed through my internet trawling that Noritake glass was made by Marti Glass.
