Over the years, I've accumulated a number of jumbo card effects. A number of my Jumbo cards are beginning to curl. Wondering if there is anything close to a "card Guard" for Jumbo cards? If not, would like to hear how you store and transport your Jumbo cards.

I store mine between two sheets of heavy cardboard (like the type used to back legal pads), with the whole shebang inside a large tinted see-through plastic envelope (the kind with the string closure). I use a different colored envelope for each set of props.

I decided to make up some "large" slim card boxes out of heavy cardboard stock.
