Gemini Black ABS Plastic bullet Jars 350 ml and 550 ml SAGEM Mixer Juicer Jar  (850 ml)

Liked the concept of the bullet system attachment to my regular mixer machine, it work wonderfully because this system is much faster than the regular jar,
However there is 1 drawback, there should be grip outside the container rather than inside walls, because due to the smoothness of the outer portion it's gets difficult to open the jar from the mixer attachment specially when the hands are moist or wet.
