. Well, when you first use them, it seems so. I didn't find them to last as long as Brother. They don't empty completely. The printer said blank. I took it out. Put it in our ammo box. After a while, as we approached the box, we found that the ink had spilled all over the box. I'm so glad it wasn't sitting on something that could go bad. otherwise it would be damaged. I won't be buying these again either. They don't last that long and you never know if they're really empty or not. If the printer says they are.
