Welcome to the forum , KelliBelli .
Wish I could tell ya' , but I don't know .
The style seems west African to my old eyes , late @ night ....
I'd suggest that you look for signs of wear , in areas that seem 'natural' to the touch & base & so on , as towards getting some idea if your cool little items are recent manufacture , or well-used & older !
Sometimes items like these (for the tourist market) will have a distinctive 'waxy' feel to them , and can be made to imitate the look of 'authentic' items .
Can't really tell how large they are ..... looks as if there is a soldered/brazed joint in the neck of the round one .
Travels in Africa will often turn up some rather creative metal & claywork examples , some sorta like yours , for use within households ... holding oil , water & milk & such .
Regardless of all that , they look like cool hand-made folk art items !
Have you checked these little fellers with a magnet yet , KB ?
