It's a dutchie, you just get the ends real wet, and they are fairly pliable without ripping/breaking. It definately helps you get the ends tight when you can't quite pack effectively. When you cut the ends right it makes the PERFECT mouthpiece. No weed flying into your mouth because it it packed nicely, but a big hole to drawl through.

If you look closely you can see the ends are still damp in the pic. It takes about 10-15 min to dry, or about 10 secs on a lighter flame.
