i can supply the custom printed phone cases, the materials of this type case are usually TPU and PC,
The production process of this Phone Case is not the same for different phones, such as Apple, samsung, Huawei, and xiaomi.
The printing process is also different, just as the plane design, embossed effect, set with diamonds.
You only need to provide pictures or logo you want to print,and then tell me the phone brand and model.
I just help my customer made 4 k + custom printed cases for iphone 6 last week.
if you need ,PM me
