Set of four dividers for a K'NEX Storage tray Grey or Yellow - the tray used in many larger K'NEX education sets.
Creates 6 compartments in the tray, allowing your K'NEX or Kid K'NEX parts to be stored by type. See photo, but note that the tray itself and the K'NEX parts shown in the photo must be obtained separately.
Makes finding the part you need much easier and quicker!
