Is the cartridge that comes with a new 510 atty usable? Some suppliers call these dummy carts and say to throw them away. However, they fit well and look identical to a regular cartridge. Seems like you just need to add your filler material and not have to buy the cartridges?
Thanks for any help.
Ditto - I keep all mine and re-use them. They get 'baggy' over time so having a bunch is a good call.
What do they look like when they get "baggy"? I'm still using some of the same ones since Oct '09 and they seem fine. I wouldn't want to be PI by ignorantly using baggy carts...un. 8-o
