Wasteful.

The good: - Very pretty - Smooth - Ink similar quality and look as Gelly Roll Metallic The bad: - Ink very quickly runs out, don't get attached to the colors - Not all of the ink will come out of the cartridge, you will have streaks and blobs left unused and wasted inside - Glitter all over your life forever I like the pens, but I bought them to make notes and outline stories with. I wrote six pages--three pages front and back--and had to refill the pen because it was out. Then that refill lasted for not even two pages front and back. A third of the ink is left in streaks inside the cartridge. I'll have to look for an alternative for my writing. I can't imagine these are very reliable for anything but tiny notes or small art pieces.
