I shoot on m4/3, so most of my filters are small. Most are 46mm, and the largest are 58mm. All the filter storage options are either large folding jobs that are long and wide, or are sort of stacked up but for large filters. I’d ideally like something like this, but for filters half the size.

What’s your best filter storage solution for say 10 filters, either 46mm or 58mm?
