Buffet dispensers (4)
I believe the answer is:
urns
'buffet dispensers' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for urns that I've seen before include "Tall vases" , "Funereal vases" , "Grecian vases" , "Vase-shaped vessels" , "Runs to get large vases" .)
