In a quick update, we've actually stopped using this because of...strangely...the smell. I don't know what they use to treat the material on the inside of the case, but it STINKS of fish. Initially I thought it was just the air sealed in the packaging and that it would be gone after a wee while of airing, but no, it persists. The smell is even transferring to the back of the Elonex. It's so off-putting, and quite revolting. We've tried to soak it, spray it, air it...nothing makes a difference. To send it back Hong Kong will not be worth it as it only cost a tenner. Be wary!
