Many years ago I had my mothers extensive collection of Kilner Jars,
these were the type with a metal lid and metal screw band. After some
years it became impossible to obtain the lids, which only lasted a few
times. With great reluctance I threw the jars out and bought the new
type with glass lids, separate sealing rings and plastic screw bands.
Alas these have now become obsolete and they are now making the metal
type again, what a rip off.
Anyway moan over, how good are the type with a lever and clip to seal
the lids? Which type do you find give least "failures".

I use the all glass type, with the wire round the lid. Come in varying
sizes, perticularly in France) from 0.25l upto 1litre (or possibly 2).
Rubber sealing rings are quite good, and can be used many times,
provided you can open the jar without damaging them!
