Is it an impossible task to find something that hangs on a long string or thin strap around your neck that you can carry just your essentials in, like money, keys, credit cards? I'm feeling the need to have something like that for places like the playground. It could be bigger than needed for just your keys, money and credit cards. I'm thinking like a wristlet, but with a long strap. Something a bit fashionable, not like something you get in a travel store. Thanks so much!
