Trade/Selling Henry's Viper Barely Used

Hey all, I have a Red Henrys viper I’m looking to trade it for any 1A play yo’s or maybe a looping yo. I will sell it for any reasonable offer. There is a tiny color mark on one side (as pictured), barley noticeable, doesn’t affect play, and a small knick on one side, that also, does not affect play. Not to mention they have replacement shells if you don’t like red, or just want new a shell!
