Set of 3 glass scientific laboratory cones.

Slightly different sizes - 1 is shorter.

Sizes:
Height: 3.25 & 3 inches; Diameter 2 inches.

Combined weight: 650g (allow 1 kg 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?
