In March, I bought a phone case. I'm always concerned with stitching when I buy leather goods. The stitching on this case is great, except for two stitches on the side where there is a little bit of thread coming off. That is, the main stitch is holding but there are a few strands of hairs coming off. Should I take it back to be inspected? I don't want to be too picky but I also hope that the problem will not continue getting worse. I find that every time I use the case, I check this. Perhaps, for peace of mind it would be best to have it fixed/exchanged. Since it is on warranty, will they be more likely to try to repair or exchange?
