It has been months since I have posted but I will try and be more consistent.
So, lately I have been in search for the above bottles.
They are called Demijohns and they were used widely for brewing and holding wine.
Now they are mostly used in decorating and some even collect them.
I love the beautiful green color and the curved shape of this object.
They can be used for decorating a room or even to hold flowers.
I find them so interesting and mostly love that they were air blown and molded.
First three images via google. Last two taken by me.
