Perez-uzza to this day
They do, but it is not paper. It is a pretty sturdy fabric of some kind. You'll wear out a carto eventually - then you can just pull out the stuff in one peice with needle nose pliers, unwrap your little extracted package and have a look. I used to have a real problem burning up cartos, but once I got over that I found them to be my favorite atty.

Copied from another post, but here were my problems and the fixes that I picked up along the way:
....................................................................................
I’ve found that the problems I had before with the KR are all easily remedied just by being aware of what is causing the problem. Here are the problems with their solutions:

EXPENSIVE??? – No.
They are expensive if you treat them as disposable. You treat them as disposable because they are advertised as disposable, they burn filler when dry, they don’t perform well if you refill by the wrong method, and at first they seem to be a pain to refill. Once you learn that these things are not true (explained below) you will find that you have discovered the cheapest atomizer on the circuit. Depending on where you buy you can get five KR cartos for the price of one 510 (or 801, or 901, or any of the RNs). Even cheaper if you buy blank cartomizers in bulk, though I usually get a mixed pack of pre-filled cartos for a cheap way to try new flavors.

CAN’T DIRECT DRIP??? – Yes, you can.
It is a misconception that you can’t direct drip the KR. The KR is the best direct dripper out there in my opinion. People think you can’t direct drip because there is no bridge, no mesh, etc. The KR has the atty coil (the part that vaporizes the juice) wrapped up in the filler. It eliminates the mesh bridge over the coil design found in most attys. When you drip on most attys you are simply keeping the mesh around the atty wet. When you drip on a KR you are simply keeping the filler wet. You should NOT try to direct drip down the hole in the middle of the filler directly onto the coil, you aren’t trying to drip right onto the coil in any other model, don’t do it here (try it once if you want to know why, it just doesn’t do the job). You direct drip the same way you should refill – right onto the filler to keep it full and wet. A wet carto on a pass-thru = truly great vaping.

A PAIN TO REFILL??? – Not really.
There are two methods to refill. The first is to drip through the battery end. Try it sometime. The problem with this is that you are refilling blind. You often end up over filling, which reduces the performance of the cartomizer and leads to frustration or the belief that a good refilled cartomizer is “hit or miss” and you just have to get lucky. So, yes, it is a pain to refill this way – though most people try it because it sounds easier than the other method.

The second way, the right way, is to pop the plastic tip off and pull the little rubber ring out and drip onto the filler to fill it up. The reason people avoid this is because they think the plastic tip is a pain to get off. It is…unless you have the right tool, which is something most people do have. A screw. A drywall screw is perfect, any normal size screw will usually do. Just screw it into the air hole of the plastic tip and pull. The even pressure of pulling from the center pops the top right off easy. Every once in a while you’ll get one that is on too tight and you end up mangling the plastic tip…just use these “tip-less” carts for your direct drippers or use the tip off of a throw away to replace the mangled tip. Another convenience of the screw is that the head of the screw is just the right size to push the rubber ring back down over the filler. The rubber ring is non-essential, it servers to prevent leakage, so it is not necessary to vaping if you aren’t carrying the thing upside down in your pocket.

Now, a quick tip on filling: don’t overfill. Once you see the liquid at the top of the filler (usually 16-18 drops on an empty cart, 12-15 on a refill cart), stop. No need to try and squeeze one more drop in. If you flood this atty it reduces performance until you vape or blot it to an un-flooded condition. If you do overfill just roll up a tissue and press it against the filler, turn the atty upside down for one second to soak up any excess juice, and then you are good to go.

Another tip: After extended use you may find you have “dirty old juice” in the atty – you see that with any atty. While you can wash it with hot water like other attys, you should know you can also drain out the dirty juice like other attys – roll up a paper towel or tissue, press it against the filler, turn it upside down and let it drain into the tissue for a half hour or so. I personally never wash an atty, it is too much of a pain, draining the dirty juice is sufficient for me. I just break out a new cart if I want to fill with an incompatible flavor.

BURNS FILLER??? – Not if you keep it wet.
It burns the filler when you vape it DRY and there is no juice to vaporize. Don’t vape it dry. Don’t even vape it mostly dry, unless you want to bleed it dry and toss it, which is a little like making grilled goose when you could have golden eggs. Grilled goose is good, golden eggs seem to be a better long term plan. Remember, now that you are a refiller and know you are just going to put more juice in the atty, you don’t have to be concerned about sucking that last penny of juice out of the carto before throwing it away.

As soon as you detect a flavor change, reduced vapor, or feel like the carto must be going on empty, just set it in the refill pile and bust out one of your ready refills or a new carto. There is no magic sign when the cart is going low – you just get a better feeling for it once you’ve vaped KR cartos for awhile, be prepared to waste a few cartos during the learning curve. Just keep in mind that it doesn’t matter if there are still five drops in there when you decide to refill. It does matter if there is only one drop left and you are still vaping away on it! The trick to not burning the carto, smoking filler, or ruining the carto is simple – keep it wet! Switch to another carto when you sense it going dry. If you are direct dripping at high voltage this is not a problem because you left the plastic cap off and are refilling every 5 or 6 drops of vape.

RUNS TOO HOT??? – C’mon, do you really only have one battery?
Contrary to what might seem obvious, this is more of a problem at 3.7 volts than 5 volts because people vape longer and more repeatedly at lower voltage to get the same amount of vapor. When using standard 3.7 volt batteries, I usually carry four loaded batteries with carts on them in a little wallet size pocket knife sheath. Heck, sometimes I even shotgun (vape two at a time) for a quickie. Anyway, when you feel a cart getting hot switch to your other battery (easier than swapping carts off the same battery). This also helps prevent the filler burning problem. Getting a carto hot is the only real trouble with the KRs, but it is only trouble if you only have one cart to vape.
