So long as you are careful and patient, this pencil component is easily refilled
and reconfigured. Better yet, now there are style/fit bodies with erasers, so
you can advance the lead from any slot. Presumably this means you can now
install several in the same body. The only problem is a little noise while
writing, but that is the fault of the body, not this component.
My briefcase has a false "belt" strap and no pen pockets; however this case's
snap design allows the whole thing to clip around the side strap *perfectly*.
The zippers can be a bit slippery to fumble with when you don't have both hands
free, but this is a fantastically useful case nonetheless.
