Everyone of our unique Books-in-a-Cup is brimming with delicious entertainment for solo or group travelers. Every flavor, from grape to orange to lime, is packed with four unique 40-page activity books, two sheets of stickers, a pencil with an eraser and a cool critter pencil topper. Best of all, they fit neatly into an automobile cup holder to keep even the most restless backseat occupants zooming along at a hundred smiles an hour.
