Pair Bidriware ? Wall Vases

Is this considered Bidriware? I guess recent pieces?

 

Certainly Bidri, I've not seen them as vases.

 

Yes, Bidriware, and a very nice set too. Most Bidriware I see is vases, but I've never seen wall vases. I have no idea of the age, sorry.

 

I’ve always wondered of those type of vases. I had a pair of Chinese porcelain with similar shapes. They also had holes on the bottoms and I wondered if they had multi purpose like either hang them on the wall or tie them together with a string or so and use them as a double well table vase.
