You've splashed out an expensive gadget and taken it to the beach or poolside. What happens? It gets wet and you only have your now very stroppy self to blame. Or you could stick your mobile/ camera/ iPod in a waterproof case from Celly and be thankful that at least you planned ahead. Available in pink, orange, yellow and blue.
