Made with a soft durable cover and elastic closure, each puzzle book contains 115 puzzles with solutions included on the rear pages. The puzzles range from easy to very hard, and are available as singles or sets.

Practical, lightweight and easy to use, each book can be carried alone or paired with Twig & Leaf A6 refillable covers.
