Unless it's something else, I think you can find these from a bunch of different sellers in the USA (also by searching
ebay and amazon, though Amazon's
search tool isn't efficient to use). I believe I got my case with Lighthouse trays from
Wizard Coin Supply, although that listing is for the small 5-drawer one, but they've got the 10-drawer ones too. Here's their listing for
the drawers/trays with spaces for 20 coins in 2x2s. If you click around the links, you can find other stuff on their site that might
work (but some of it isn't always easy to find).
Finding this stuff is all about using the right
search words (either when searching with
google or navigating a supplier's categories). The key for these ones is to use the term "Box" -- they're "coin boxes," no use of the words "tray" or "drawer" in their listing (which I don't get, don't they want customers to be able to find them?). It's like that for most retailers. The case is an "aluminum case" for "coin boxes." Using those
search terms will
help you find other retailers in the US on
Google.
BTW, I've been very satisfied with mine. Not the highest
quality trays like Abafil, but they
work for storing and presenting most of the coins I keep at
home (vs. in the safety deposit box). Also, because the flock inserts can be taken out, I use the plastic drawers for various other numismatic and/or literature displays.
