At
www.ruyandirect.com you can get either the black cigarello or brown tube type. The brown holds more
juice I find but is harder to pull off. It is also easy to clean the carts and rejuvinate the filling. Just soak them in extremely hot water, I boil some put it in a bowl and
throw the used carts in. Let them soak a bit, change out the hot water lte them soak some more, then blow out the water after they cool off. I put them either on some paper towel to dry or in a collander and set them outside in the sun to dry. I've done this with 401 carts, Npro carts and 901's. Afterwards the filling seems a little denser but this is not a bad thing.
