Do the iphone 5 cases fit on iphone 4?

I what to buy the retro vintage cassette cases with the 8 pack for my iphone 4 but it only comes in iphone 5

Pretty certain no. The 5 has a larger screen so it's gonna use a larger case.

Not even close. They r 2 different sizes.

Probably not, because the iphone 5 is longer than the iphone 4, therefore it would not work.

The iphone 5 case will not fit the iphone 4 case. The iphone 5 is slimer and longer than the iphone 4.
