Vase with a small tube at the bottom inside

[Ragna]

Hello,

maybe someone here can help me with this. As you can see in the picture of the inside of the vase there is a small tube at the bottom.

I haven?t seen something like this before, does anyone here know what it is used for?

And do you know if it is a asian or a european vase?

Many Thanks.

In my view this is modern and possibly western.
