Be careful if you buy the cubes -- some of the dies are duplicated in a couple of the cubes so after the first cube, the rest may not be as good a buy. Also note, if you buy the 6" cube (for instance) you will not get a 6" (finished) die. Also, make sure you use a mat with each die you use (and different dies may need different size mats) -- your dies can/will get messed up if you don't use a mat. When you look at a die, if you scroll down and click on the "Details and dimensions" tab you will find the size mat needed. Mats DO wear out so plan on replacing them so watch for sales.
