Pillbox, improved rolltop design

This an improvement on a previous pill container I submitted. I liked my previous one as it solved the issues I had but the top was removable and I thought I could do better if I could design a rollmop lid. This does the trick.
Still holds all ny pills.
Still stackable (I do a month at a time so they stay together in the drawer).
I can tell at a glance if I have taken todays pills.
Very easy to refill as the top is wide open so just need to drop the pills in.
