This is a case to suit a China Mobile A3s phone, (M653) which at the time of publishing this part, has no commercial cases available.
I spend a lot of time outdoors and in workshops so I need a well protected phone.
The attached files show two versions. One with text and one without.
The choice is yours.
Sorry about the poor quality photos, just one reason why I wanted a new phone.
