How big is the GAC?

[saymama]

I'm looking for something plastic to slip it into when we go. I need to know about how big the GAC's are so I can find something close. I'd like to maybe get something plastic and hang it on a lanyard or somehow attach it to the medical stoller that we are using.

Last time I had a fanny pack and put it there, but I don't want to wear one this time.

What do you guys do with yours?

It's 3.5 inches by 5 inches.
My DD has a backpack that is always on her wheelchair. We put the GAC into a small front pocket of her backpack.
I didn't take it with me, but I had a lanyard with a pocket that was just about the right size that I got at a convention last year. I know some people have used somthing similar to that to put their GAC in. I've seen similar pockets at Office Max or Office Depot.
