Jepps are, strangely enough, a US size. 8.5 by 5.5 inch or half letter. You might try Legalstore.com or do your own search for "half page sheet protector". You will have to order from the US and pay the associated currency conversion and post but you won't pay anywhere near Jepps price. If you do go down this road, post so that everyone who is annoyed by the
2mm sticking out the top of their A5 pockets can see the alternative.
