Neoprene Ipod Sleeve

Original neoprene case/sleeve that comes with the older iPods?

Hi, does anyone of you know where I can get the original neoprene case/sleeve that came with the 5th generation iPods? That casing was probably the best I ever had, it fits my iPod perfectly and protect it from scratches. I've been looking for it everywhere ever since I lost mine but sadly, I still can't seem to find it. It'll be really nice if any of you can direct me to an ebay seller or any site in particular.

In case any of you have no idea what I'm talking about, here's a picture of the case.

I have not seen those on sale for years although seen ones similar, very few of them though, at Best buy and the apple store in my city.
Or you can check out the Marware website, they have a large selection and may have something similar.
