Try the sporting goods section of a local store as well- tackle boxes to be specific-
There are some smaller ones available, some are slim and the dividers are either adjustable or can easily be cut out to hold the items you want. For my 650 batts, I used a small plastic pill box of sorts that my wife picked up in the "travel size" section at wal-ly world. Holds 1 spare batt. 2 cartos and a 3ml bottle of liquid. I'm sure there are shapes and sizes galore at craft stores as well for holding beads, etc.
And plastic is nice because you can wash it out if your bottle or carts leak.
Just another option to consider...
