Where to store the Razer Naga Pro Wireless Mouse Side Panels?

Hi,
I recently purchased the Razer Naga Pro Wireless Mouse and I am really loving it! My only thing is I don't want to damage the extra side panels when I am not using them and I was wondering what other people do with their mouse side panels to keep them clean and protected?

I mean I could leave them in the box, but it is a bit of a hassle to get them out the box every time I want to change my mouse.Whilst leaving them on my desk is asking for them to get scratched, dusty or damaged.

I'm just wondering if there was a bag or box or stand people used to store them in, and if not maybe it could be a great product to make. Love to know how people get around this.

Cheers
