JB,

this line of Epson carts uses a sophisticated valve that prevents leaks or 
drying out. In fact, because it is proprietary to Epson, third party carts may not 
have it (and so beware...). 

As others have said, I too, just stick the half used cart in a ziplock for the sake 
of not pushing my luck. Officially you are not required to do this. Swapping 
works fine and is safe to do with Epson inks and carts.
