High quality disposable plastic tattoo tubes make life a lot easier not having to worry about the time spent scrubbing tubes or making sure that your autoclave is constantly working properly. The rubber grip helps reduce the vibration and hand fatigue. Just open them use them and get rid of them. A small price to pay considering the time saved and no chance of cross contamination from one client to the next.
