Bookend... real? value?

[pomodoro]

Bought this a couple years ago. No chips, in excellent condition.
I wonder if it's real and who made it, what company and how much is it worth.

Hi pomodoro (tomato), as I can see at the moment the bookends are made in sommerso and they look like Murano. Same as Cenedese made it designed by Antonio da Ros but andditional pic of the base is needed also the sice to comment a value. Are they signed?

Thanks for the reply. No they're not signed, no labels.
Here's some more pics.
Your help is very appreciated.

Note: there's no scratch just a bit of dust on them. Shame on me

As I stated they are made by Gino Cenedese and the value is 100/150 EUR,
other may differ.
