Tupperware hand chopper Chop N Prep

It is a hand held chopper. You twist the top back and forth to spin the blades to chop. It works well. Have not used this one. The blades do pop out easily for cleaning. When I was testing this one, it does seem that it will need cleaning as the spin of the blade seem slow. It has been in storage so that is probably why. Size is 300 ml.
