Good product
I still don't know what the Akashi brand is worth in terms of smartphone cases and protections. However, this product looks pretty well designed to me.
The phone's location is a soft protective shell, so you don't have to worry about the hard plastic cracking at the slightest impact. The card holder is a small plus in favour of this product even if it seems a bit fragile. One of the most interesting points is the possibility to use the case as a stand to place the smartphone horizontally.
However, I do not recommend placing a card whose operation is electronic (bank card, city transport card, driving licence, etc.) near a smartphone, as its operation could be impaired.
All in all, this case is a product that I recommend. Inexpensive and practical, it will protect your smartphone against bad weather and shocks.
