If you are more Interested in access than protection, then you could consider magazine slipcovers. They are basically boxes to store them in. The downside is that they don't offer much protection from being, etc.
Here is an auction the type of item I mean. You can find them without any branding. Maybe you could find one with a Yankee logo if you look on etsy or similar.
