Hey! I'm a new poster but have had MLPs from the get-go. (I'm 30 so you can imagine). My question is about the Birth Flower ponies - I have the entire set, and I'm pretty sure they all have their biography/pamphlets about their birth month and flower intact as well. I'm going to try to list them on eBay but wanted some opinions. Do you think it's better to sell them one by one, or as a whole set? See pic below.
