Kassa book and a naturally shaped black kassa (natural stone). Convenient with a strap. From over 10 years ago. Both the kassa and the book have been used. Stored at home without use for a long time. The book has stains and spots, and the kassa has dirt and small scratches, but no cracks. Please be sure to check the images. I am selling because I have another kassa and don't use this one. For those who are thinking of starting to use kassa, how about it?
