Hi,my friend,thank u for your response and we are really sorry to see that,as we got that two cases from different surplers,the size are different as well.We would like do something to compensave u,but i think the size of window is not effect when u use the case.So would u mind closing the dispute when we give u 2.5usd refund?As seller,we are not easy,please understand our situation and we would give u some discount for your next order from us.Please let us know you idea freely,waiting for your reply
