Seen these in Poundland. iPad screen protector and also next to it was an iPad Flex Case (description states 'cushions and protects so looks like a diff type of protector).
I think they would also fit the iPad-2 however you might need to 'punch' a little hole so that it doesnt cover the front camera on the iPad2, if you're not fussed about the front camera then I believe these would also fit the iPad2 no probs.
On a separate note, dont know if you can see the pic at the bottom but they also had neoprene cases for netbooks and laptops all at £1. They were the same product as I paid £6 for a while back for my netbook so looks like good stuff.
