This xylophone has a ''stereo sound chamber for full rich notes.'' Don't get too excited, the sound is only fair, but maybe if you know what you're doing you can make it sound much better than I did. It has ''.. 8 accurately tuned aluminum tone bars.'' This little toy was made by the Plastic Injector Corp. a subsidiary of the Wm Kratt Co. The original box has wonderful graphics. The xylophone, hammers, song book and stand fit snugly inside the 17'' x 7'' x 3 1/2'' box. It's in very good condition.
