Dripping is not into a carto. Dripping is into an atomizer on a manual battery ecig (not recommended for auto batteries
If you want to drip into a carto you can buy a drip-o-mizer but they are $4 apiece and I heard people get shocks on them because they come with metal drip tip
I do use plastic or delrin a drip tip on a carto but only as a comfortable and easy-to-remove mouthpiece. My cartos have a defined central air channel (Boge, V4L) so I don't attempt to drip into them through a drip tip. When I add
juice to a carto I remove it from the battery, pull the drip tip, tilt it, and drip a bit of
juice into the stuffing (if adding a lot, I hold a bit of tissue against the thread end hole). Then I clean it up if necessary, puff into the threaded end to clear any juice from the air channel, sop up any loose juice on the top of the stuffing.
Do you mean you removed the stuffing from a carto to use it as an atomizer? I've never done that but I imagine a Jumbo might have more blank space between the wicks? No idea, never done it. I use an atomizer to drip. I use DSE901 on manual KR808D-1 (Vapor4Life) and Joye 306 on manual 510 for dripping.
