Peli 1020 black

I own several of these small Pelican cases. I use them for travelling (usually keep my earphones and small connectors, powerbanks, etc. in them), and never failed on me. Not once. I even use one in my jobsite bag. A bit expensive, but... yeah. It is, what it is. If you have the money, absolutely recommended. If it is a bit steep for your budget... there are very similar, lot cheaper, but also lower quailty micro cases out there. But these might(?) survive a nuclear blast. Those most likely not. So... depends on how rough you are with these.
