What I do is cut them in 4ths. So they're all rectangles.
Then I roll one up, stick it in, and bend it where it sticks out.
Pull out, unroll, fold at the bend, then add one more little fold (usually in the same direction if anyone wonders) to add some space for the atomizer to come down into the cart.
It holds 15-18 drops on initial fill, and I get 9-10 drops on a refill.
They are prone to leak if jostled much, but it's worth the effort to just take off the cart and cap it to prevent leaking.
