Full Turn Cube is a fully un-functional 3x3x3 Rubik's Cube. Whereas Half Turn Cube supports only half turns (180), Full Turn Cube only supports full turns (360 degrees). This is achieved by offsetting all six rotation axes a bit.
The purpose of this puzzle is to demonstrate Rubik's style turning to children without the hassle of solving the puzzle every time that they scramble it. The purpose of this puzzle is also to confuse cubers for the amusement of its designer, and perhaps some inspiration to other cube designers.
