I've been trying to find a little box, similar to the old tool box, but rectangular. In my job, I need to carry smaller items, and it needs to lock. I do have a larger ballistic nylon carrier with a solid inner lining. Fitted to my detachable rack it not only sticks way out to each side, but it's a pain to throw your leg o'er. I'm looking for a chromed, lockable box a tad smaller than a jewelry box. More flat than wide. Once locked, I want it firmly affixed to the rack, and I have strips of live rubber I can cannibalize for cushion between the box and the rack. Ideally, you wouldn't notice the thing if you walked by the bike.
