is this what you're looking for? i want those too but haven't recieved my Riva kit yet, and have no idea what kind of cartos it takes. i think 510s will work, someone correct me if i'm wrong. still new to this.
510 Kits
That's the first I've ever seen of something like that. Good find! However, it seems he doesn't sell just the Mega LR Cartos alone.
I sent a message, so we'll see.
"I see the 510 Low Resistance Mega Cartomizer Kit on your site, it comes with Mega LR Cartos?
I don't see just the Mega LR Cartos for sale on your site, and that's what I am looking for.
I have an eGo and I'm using Boge LR Cartos, but would love bigger ones.
Please let me know if just the Mega LR Cartos are able to be purchased without batteries, etc.
Also, are they soft-capped (easy to remove the cap and refill) or do I need a syringe?
Thanks!"
EDIT: Yes, Riva uses 510s.
EDIT 2: Of course, they must be the real thing, lol...reasoning being-I just ordered 10 LR Cartos last night. D'oh! We'll see. I will keep you posted as soon as I find out.
