There should be a way to make an item unsellable. Let's say someone meant to sell a pet, ( Not many people should do that. You can't sell pets for very much so if you want a pet to get out of your backpack just put it in your house.) but you accedently sell your favorite pet that you spent so much time leveling up to mega and it wass alot of crowns. You would be seriously devestaded! Many dollars and time could dissapeer if you accedently move your mouse a centimeter away. So I think you should have an option to make something unsellable.
