This item is a full box of North Pacific Products Whirl-E-Bird Boomerangs. This is product #329 from the 1950s. The box includes 36 individually sealed boomerangs as well as a single display boomerang. The box has been opened, but the contents are new. This is a really nice short range right or left handed boomerang that really works well. The short blade is attached to a sliding plastic sleeve that slides along the length of the long blade. This enables you to throw a variety of shapes ranging from the letter " L " to the letter " T ". These adjustments modify the flight range and height of the boomerang. These boomerangs not only work well, but they are really good collectibles.
