Nike dry-fit tee t shirt short sleeve XS

Nike dry-fit short sleeve tees in great condition. I'm selling them as a pack. I bought the pink one first. I liked it so much and then I went back to get the purple and blue one. I thought they're all identical, but today I realized the blue one doesn't have the dots on the back (see pic). There is nothing wrong with the shirts. I just don't exercise that much recently. Let me know if you have any questions. Thanks.
