Còi Tàu Hỏa Bốn Âm Cổ Điển

Same train whistle as when you were a kid. Produces four different tones to mimic real train horns. Re-live your childhood, and pass those memories to the next generation. Print vertically, with the mouth piece down to accommodate the internal design. The small whistle in the pictures is printed at 50%. Works perfectly, just with a higher pitch. Great size for the little ones.
