Cheap plastic travel soap containers might look like they were made for bars of soap, but really they're ideal for card games.
If you've ever had a deck of cards mysteriously lose a member of the pack, this is a smart, yet simple solution for you. The soap box is easier than the original cardboard boxes to put the cards back into -- and that small difference might be all that it takes to stop losing cards.
Those travel soap dishes are handy for so many other things as well, so hit the original post for more ideas.
