Each tile measures 6" x 6" and approximately 3/8 thick. The clay is very white, unsigned, and there are five circular divits in the back. Probably to help them keep flat during drying.
I've searched and can't find any exactly like these. Each tile weighs a bit under a pound, so the box will be heavy.
