Those look awesome wolf, I would be very interested in getting some of those.
I know you’re in Canada, so not sure how/what your limits are to shopping or ordering online, but here’s a link to the organizers from Home Depot online… if nothing else, you get “the official” name.
I use these for the nation trays
I use this for the accessories
Of course, use them as you will…
As for my flags, I just used Vistaprint and made some small rectangular product labels and you upload your pictures into them… perfect for national bin flags… I made sure to use era-appropriate flags (like the 48-Star American Flag)
