The Interesting Trade

So, this guy really wanted my Zombas, so I gave him them for Saffron Photons and Sienna Spiralis. The thing was, he wanted the painted ones lol. He never specified, and blindly hit accept right away sounding so excited. Than.... he realized they weren't the ones he wanted, and he asked for the items back, it's such a profitable trade, and a bad mistake on his part. I wasn't even scamming lol. Should I give the items back or not?
