if like me you have the Genius Brand cut vegetables and are somewhat frustrated (e) only have one sealed box, you can quite buy this kit. Contrary to what the picture might suggest, these two boxes are of different height, the smaller of the two being an exact replica of the one supplied with the nicer dicer more. the other being higher you can store more fruit / vegetables. the cover of the nicer dicer plus fits perfectly so you can use them for different preparations and store then.
careful, however, as the basic box, I find the very fine plastic hinges, handle them carefully if you want to keep them long.
