When I used an android phone I had the same phone case for 2 years until I got tired of it. Now that I got an iPhone this year I got it one case for 7$(I knew I could go caseless for a few weeks because shein has some cases for 1$ but I was impatient and I heard those break easily, also when I saw the apple logo on the back on the case I was like "That's the exact phone case I wanted!") but I still bought my phone a purple phone case. Then i saw this pretty clear phone case and I had to buy it too. But a while ago I had to buy something for 1$ to get a discount and I had to buy another basic clear case. So now I own 4 phone cases and I switch them some days. I want to buy more cases but I am just waiting for the clear ones to turn yellow so I can throw them away. If I am buying a case I need it to be justified.
Just the one, I usually replace them every year or so, so with every phone I've owned I go through 3 or 4 cases.
