Using your cutters:
As with all cutters, especially the small ones, clay can sometimes stick inside the cutter, this is inevitable but it is advised to dip your cutter in water or a soapy sponge before you use it, this will act as a release agent. You can also use cornstarch in the same way.
 
These cutters are pre order- they are made once order has been placed. Currently 1-3 working day processing time.
