I have a couple ammo boxes for my samples, and I use repurposed face wipe containers or small containers from craft stores to store my drams. I have a neutrogena wipe container for my tall drams. For my FS bottles, (3-10ml), I usethis container from Amazon, which comes with a pack of labeling stickers. I like it because each bottle has its own cushioned area, and it’s tall enough that when I zip it closed, everything still fits.
