Well, there are cases, but above all, I'm worried about my iPhone5, so I'm wondering if I shouldn't try it this time. I think it's okay to conclude that it's broken.

■ Conclusion "Senbei will do its best unexpectedly"

At first, I was afraid that the rice crackers would break to an irreparable state during the experiment, but the rice crackers did better than I expected . Many people will say, "It looks a little ...", even if they understand its high performance. However, it doesn't feel strange when viewed from a distant place, and above all, it has the great advantage of being eaten when hungry. If it can cover the weak points of humidity, it will be the best iPhone case ...?


By the way, this iPhone case is pre-ordered because it is handmade by the craftsman "Mariko-san" one by one. The number of production per day is good, about 3 pieces, and the price is 3,818 (survival) yen. The sale is limited in quantity, and the sale will end when the planned number is reached. We recommend that you purchase one for everyday use, one for rain, and one for your friends' touches, "three in total."
