Pack of 4 well used hot wheels boosters. The mechanicals of all 4 boosters are perfect and have been fully tested. The track connection points of the grey boosters are worn but are all still there. The track connector points on one side of the red booster have snapped away. All boosters can still be used. Please bear in mind that they are all sold as heavily used boosters due to the state of the track connection points. Each requires 2 D batteries to work.
