Water Resistant Cases

I remember these water resistant cases from being a child and found them fascinating; they felt like a gadget to me, I could see through the sides and play with the coins and keys inside and best of all they floated.

As an adult; why not - they are really handy to just keep coins, notes, credit cards, keys and all sorts in one handy place that happens to be water resistant, all in one place and not in my beach short pockets where things always fall out, and better still, not in the bottom of a sandy beach bag.
