Much prefer to keep hooks in either soft boxes or original plastic bags. Same is true with beads. Let's say you drop either on a hard surface. What will happen? Now try the same with a pill box. Results will not always be the same. Add to this the fact that any pillbox is going to take up more room in the tying kit than the usual plastic bags, and I never quite understood why someone would want to go this route. YMMV.
