This gift is sure to keep their mind sharp! We've gathered some of our favorite puzzle books and placed them in a holiday themed gift box along with a pen and pencil, holiday fortune cookie and a bright holiday balloon. The books include word search puzzles, crossword puzzles, a Sudoku puzzle book and a variety book with all types of brainteasers. Our holiday fortune cookies arrive in a cute take-out box and the balloon is a festive finish to this merry gift!
