The book comes with a large poster, one side has the Fairies, and the other side has some more info and has the spaces for stickers #150 through #183. There are 196 stickers total. The stickers are sold 8 to a pack, random.
This set was apparently sold in Walmart and Target but I sure never saw it there. I ordered mine online at store.paniniamerica.net.
You can order missing stickers (or duplicates… I think I have at least 2 of every one, one for the book, and one for… I dunno, future art projects, maybe. There’s a separate site for missing/individual sticker orders.
This is one of the Fairies products I got the most enjoyment out of. I loved opening the $1 sticker packs (each with 8 stickers) and organizing them. I used one to fancy up the back of my phone. Once I had a number of duplicates I ordered the rest individually online.
