This precision-made tube is1.8" in total length and a body shell of .29" in diameter. Tubes are made in a spline mold so there is no tail cutting, and they are precise. I also take the time to cut the body shell off for two colored tubes and then apply the body color. This makes each tube 1.8" in length and .29" in diameter every time and gives me the true color of the plastic used for the body. Tubes come in packs of 25-50-100. There is a mail charge of $4.79 for the first item and then only $1.00 for each additional item. This listing is for Glows
