Muffler length approximately 1m 9cm To measure accurately, I measured starting from the "10cm" mark on the measuring tape. *The actual length is the number obtained by subtracting 10cm from the scale in the photo. This was a novelty item received when purchased online. The muffler was not used and was displayed. The safety pin was also displayed indoors, but there are some minor scratches and dirt. The product itself can be used without any problems! As this is a used item, please refrain from purchasing if you are sensitive. It will be folded compactly and shipped via Yu-Packet Post. Please comment in advance if you have any questions. Justin Davis Novelty Safety pin Muffler
