I keep a set of batteries in the dial holder, a small brush, spare set of filters and 0.7mm fishing line (to clean the vent) all in a small fabric pouch and an alternative leather pouch. Easily fits in the pocket (unlike the normal hardcases that HAs normally come with). I never find the paper dial denigrating over the time I use the six batteries. Just an alternative suggestion. I picked up both pouches many years ago with early HA purchases, but they do seem hard to find now so not sure where to get them.
