Why 2 stars deducted: firstly, the protective plastic window is the photo part very scratched and has not deduct protector for, so you can do against the scratches little. Secondly, that did not work properly with the clay. When dried, it has become totally cracked and did not look nice. Have again ordered clay and this time it has gotten better. However, it may have been due to my course, I have kneaded too short or the like ?? !!
FYI: What happens to sound brings with it, is that it shrinks during drying. I had the impressions then attach with double-sided tape on the frame, because the clay disk was ultimately much smaller than the frame and would therefore be dropped out.
