Okay, couple of things...
What are you thinking of when you say "100% eliquid"? Juice is all eliquid and it's primary constituents are PG (propylene glycol) and VG (vegetable glycerin), which are used in ratio. Typical juices are anywhere from 50-80% PG, with VG constituting the remainder. Some, however, are 100% one or the other. Was it 100% VG what you're after or some other thing? Knowing the answer to that might help us get you what you're looking for.
Most likely, the thing you saw referenced was what's called a dripping atomizer. Essentially, they're cartomizers without the batting and chimney coil - just a coil at the bottom of the tube. You drip juice into it (they only hold 4-10 drops, depending) and vape away. They're quite cheap and can last months before you have to throw them out.
If that's what you're after, here's a link

If it's not, maybe a little more info would help.
