As a newbie I have got away with refillable cartridges until now and trying to get the small plastic stopper out failed today and broke into bits! Any idea how to put something else in the hole as the air plug won't work. I need a ccs thingy know but doing one step at a time, regards, Julia

Heath Robinson here, do you really need a plug? It's not going to evaporate is it ?

If it is actually a stopper (air proof seal) you might get away with taping over the hole. depends what shape it is..

Brilliant, I'll tape over it. Was thinking the same thing this morning. Thanks guys

I'd stick with refill carts if I were you, CISS are more temperamental than carts.

bluetack works

I'd say bluetack also.
