oh i like this one !
So I've searched and searched for the perfect case. I have an Altoids Tin, a black Camel SNUS tin, but they just weren't what I was looking for. I searched Home Depot, K-Mart, and then finally made the trip to Wal-Mart. I was there for at least an hour, looking at everything from office supplies, tools, anything that would make a good case.
And finally I found this...
Walmart.com: Black Case Logic USB Flash Drive Case and it was only like $5. I'm sure someone else out there may be using something similar because it's a great case. It holds 3 complete 510s, some extra carts, and 2 juice bottles for now.
Here are some pics.
