Set of 3 glass scientific laboratory cones.
A pair and one slightly narrower.
Sizes: Pair: height: 2 inches; base diameter 1.75 inches; top diameter 1 inch.
Other: height 2.25 inches; base diameter 1.75 inches; top diameter 0.75 inches.
Combined weight: 350g (allow 500g once packed).
Reasonable condition for their age - chips and nibbles so not perfect - ie commensurate with age and use.
Not sure of original use - ground glass stands maybe?
