I would use those for small fasteners, or dried herbs (similar to original use), office supplies, or small collected objects to keep them together and visible.
Visible is a big deal, since tins and boxes require accurate labelling or opening to know the contents. Some stuff is just nice to look at, jars keep them clean.
On the other hand, blocking light will prevent fading or deterioration of contents, such as tea, spices, etc... so clear glass is not great unless kept in a closed cabinet or drawer, then you can have it both ways!
The flip-top lid with smaller spout is nice for stuff that you want just one, a few, or a small amount of, opposed to the wide mouth of the jar.
Would be ideal for control when shaking out some herbs directly into a recipe, or dispensing something round such as beads, or seeds, or ball bearings.
As a display for something like a sea-glass collection, or "really nice rocks", or bottle caps, whatever... you'd get to see most/all of the stuff, shake it around a bit to see more.
The other nice feature which you alluded to, is that you already have almost a dozen, and you seem to like the source, so there could be plenty more!
Multiples, with uniform size and appearance, lend themselves to creating a system or a repeating design. A shelf, drawer, toolbox, or case that fits some multiple of units could be an efficient way to store what you have. Even just lined up on a windowsill or your desk, the jars would have a neat appearance.
As a serial container hoarder myself, I sometimes choose products just because I like the container for now (works well, or fits my cabinet/fridge) or for later (all of the reasons above) and stick with a product. Occasionally, there's a container that I like, but for a product that I don't use, and will try to find them in the wild or ask a friend for their containers. Yep, that's a thing.
