Is there a way to remove the a item from the shop but at the same time make it so the users that have this item get to keep it like I would like to make items that could only be given out as a sort of award? or just a rare item that was only in the shop one time of year. Right now I have items I drew up like one that was just oh here this is what it looks like

I draw them my self ok well right now I just keep it stocked at 0 but I want it removed from shop so I can put the item back in the shop next year? so users that have one get to keep it all year around just for disply.
