Where can I find these kind of cases?

I have an ipod touch 5 and my boyfriend has an iphone 5. Does anybody know where I can find couples cases for those?

I had a look on the internet and couldn't find anywhere where you can buy one iPod Touch one with an iPhone one. However, I found some links where you can buy couple iPhone cases.

The only thing I can think of is if you get them custom made, like when you give people a picture and they print it on a case.

Hope I helped somehow.
