Rubber boot/tops for carburettors for Kawasaki KH250 S1 A B C two stroke triples. Still pliable for use. Rare these days. Please note that these are almost 50 years old and although fully functional, they are not new, so have marks/wear etc. Please study pics carefully, as these are the actual items that you will receive. Sent tracked, fully insured and signed for. 
Thanks for looking
