The iPhone fan scene across the planet has proved a ready and willing market for entrepreneurs marketing a range of accessories.

This may be the most idiosyncratic yet, however. One enterprising Japanese businesswoman has created an iPhone 5 case that you can eat.

Made entirely from Japanese brown rice and salt, the Survival Senbei iPhone 5 case is intended not so much to protect your phone, but to keep you going in the event of a large-scale natural disaster.

The entrepreneur behind the Survival Senbei is a middle-aged master senbei artisan called Mariko.

Senbei, traditional rice crackers, are the snack of choice for older Japanese, and Mariko came up with the senbei smartphone case as a way to broaden its appeal to the younger generation.

The cases are available to buy online at a cost of ¥3,818 (which, RocketNews24 reports, is a Japanese mnemonic pun on the word 'survival'). That works out to around £30, plus shipping.

Depending on demand, delivery can take up to a month because, Mariko explains, 'I can make about three good ones a day.'

However, before you reach for your credit card, Mariko warns customers that the case is immensely fragile and she cannot guarantee the case will reach them in one piece.

Indeed, she outlines the likelihood of the case breaking in a number of situations:

  • Before arrival: 9 per cent
  • Affixing to iPhone 5: 76 per cent
  • Using touch screen: 18 per cent
  • Touched by friend: 81 per cent
  • Turning up the volume: 50 per cent
  • Connecting to PC: 54 per cent
  • When the user is upset or annoyed: 65 per cent
  • Putting in pocket: 89 per cent
  • When dropped: 120 per cent

Despite its frailty, English-language suppliers report they have sold out of the Survival Senbai cracker.
