After testing countless disposable tubes for our brand, these were our favorite for a few reasons. We’ve had no issues with packaging being sealed properly, the grip is really hard to spin around the inner tube, the backing stems fit every machine vise we put it in, and lastly the open face mag has a lip on each side to help hold your needle in place while also helping the ink/pigment pool in the tube, giving you the best qualities of a closed mag and open mag without the hassle of cleaning a closed mag while tattooing.
