BIG CYLINDRIC.
with desing,

SMALL CYLINDRIC
with desing

SMALL ROUND
with desing

BARREL SHAPE

the 2 possibly '70s -chokers are on a thick greek type of thonging-
being quite clunky they really are not my taste at all, but in the spirit of collecting they must be important!
lets see if the image is the right size today...
