This set of 5 cutters containes 5 different shapes of splashes or splats, basically an irregular roundish shape. 2 of the shapes have been mirrored, so althogh they look similar, the ar the  mirror image of one another.
 
All of the cut-outs measure between 0.5 and 0.8 cm.
 
It is to be nothed that some of these cutters can be pretty tricky to sue and require a bit of practice and patience. 
I reccomend that you use cornstarch or something similar on the surface of the clay, to prevent sticking, as well as using thinner sheets of clay for the cut.
