New teal glitter converse — please read for size issue!

Hi shoppers! I bought these juniors Converse on Poshmark from another seller, and they looked new, teal, and glitter, when they arrived, so I paid her. They were a gift, so I put them to the side. A couple weeks later I went to gift wrap them when I find THIS “PAIR” OF SHOES ARE TWO DIFFERENT SIZES! Too late for a refund, I’m stuck. The LEFT foot is a youth/junior (big kids) size 5.5. The RIGHT foot is a youth/junior (big kids) size 5. If you’re in between sizes or maybe have slightly lopsided feet, these may be for you! (The recipient I was going to give these to is actually a youth 6, said she’d squeeze into the 5.5 because the teal glitter is HARD to find, but that size 5 right foot ruled these alllll the way out for her. Hopefully someone out there will be luckier!) They are in brand new spotless condition (no tag, no box) and coming from a clean smoke-free home, and honestly except for taking pictures they’ve been in the plastic they were shipped to me in the whole time. I realize most people don’t want mismatched shoes, but I’m giving it a shot, listing at less than half of what I paid, just to try to recoup something. Offers welcome!
