Vac form unit holds a 45 page activity pad, 4 crayons, and 6 sticker rolls with over 250 stickers! Each activity page can be colored and completed with a sticker from a roll that corresponds with the theme of the page. Grey shapes on an activity page help kids know what stickers are needed for the page. Sticker strips are also marked with page numbers to ensure the stickers will be placed on the correct page in the activity pad. Clear cover helps keep everything neatly in place.
