Wow! I can't thank you enough for sending this. It is so valuable to see what people are actually carrying with them.

That is a large spacer! I want to build my new case to accommodate spacers, but it seems they come in such varying sizes - difficult to design around.

One idea I've been throwing around is creating a compartment case similar to this: https://imgur.com/a/rMjB8

It may also have a smaller, detachable mini-case within the case, so if you want to just bring the epi's somewhere you can, like this: https://imgur.com/a/EYF6Z

What do you think of these ideas?

One other thing - you mentioned you write an entire 8.5 x 11" sheet of paper worth of information about allergies. What types of things are you writing down, and how could I better design a card, even if it is larger - like the one pictured in the latter images here: https://www.amazon.com/dp/B06Y39LWVF

Thanks again for your awesome feedback!
