Four tiny metal puzzles, one big "aha!" — the Yay! Brain Bogglers pack a surprising amount of head-scratching into a pocket-sized set. Each little tangle is designed to be pulled apart, and figuring out how is exactly the fun.

Twist, angle, and slide until the pieces suddenly separate — then challenge a friend to solve it faster. Shapes and configurations vary across all four, so no two feel the same, and the printed solutions on the back mean nobody stays stuck for long.

Cheap thrills for restless hands: an ideal impulse grab, waiting-room saver, or stocking stuffer. Includes 4 metal brain-teaser puzzles with solutions.
