They are the same as the rest, just more in the tub, with much more of the all important juice.
I have one which doesn't leak.
Some advice, you can buy bottles with the juice in aswell !
I take a tub that seals, throw all my artificial (call them Berkleys) in with most of the juice and leave them in there. When I go fishing I take out what I need, put them in the Berkley tub and go fishing, when I come back home they go back in the container that really seals properly, getting time to rehidrate.
