I just checked out the site on mobile. Clearly whatever page theme you're using was built for mobile because it's way better on mobile than desktop!Great feedback, thank you for all the detail!
Clarification, I didn't do the even more simplified categories (which would look good) because I was trying to limit clicks to get to places. Main Page -> Main Page -> Mag Racks -> Specific Rack. Technically this is still within the three clicks to get anywhere rule from 15yrs ago but what's your opinion?
As for TSA I'll add more detail. They will not allow a formal sticker because they only do that for specific items. It was cleared through my brother in law (while at TSA), independently through the TSA back office, and subsequently through use buy a number of people. The exception is that it's necessary to support life of a living animal and this the volume is of little consequence. Apparently they need to be removed from the koozies before going through the line through.
I'll think up a way to summarize.
As to the clicks, your page is very fast so I'm not sure how problematic an extra click might be. Mobile is always going to have one extra click compared to desktop simply to open the menu.
All I could find on a google search for TSA and corals was this tiny snippet on their website: https://www.tsa.gov/travel/security-screening/whatcanibring/items/live-coral. Not very helpful and sounds like you could easily get boned if you catch a TSA agent in a bad mood or something, but at least I can see why your container would be considered TSA approved. I'd maybe change word approved to compliant, as you don't really have some special approval, you just fall within the rules.
