Review: Cute - protects phone
Review: Manufacturing Defect on Case - It's a super cute case but I had returned and bought another one thinking it was only one product damage but it had the same issue in the same place. It looks like a piece of the edge was broken off. Think this might be a manufacturing issue but wanted to let everyone know.

### ⭐⭐⭐ Manufacturing Defect on Case
*by J***E on September 17, 2022*

It's a super cute case but I had returned and bought another one thinking it was only one product damage but it had the same issue in the same place. It looks like a piece of the edge was broken off. Think this might be a manufacturing issue but wanted to let everyone know.

### ⭐⭐ Marks on the edge of the case
*by J***P on November 20, 2022*

Before I purchased this case I read the reviews and saw that there were marks on the case. I just received mine and there are obvious marks on both sides of the case. I am contemplating on returning.
