I have bought several phone cases from above companies, here we make the comparison for your suggestion:
Zazzle has best quality and multipal design. And they have 3D design case. Brightent has very good price which you needn’t have too much risk. Obviously you can save a lot of money. Also, if you have good design, you can open a store on their platform to sell your design on the phone cases.
