Very good! They worked well for my purpose, which was protecting fruit from birds. Yes, I wrapped figs in a leaf and covered with a mandala... worked perfectly to foil bird attacks! They are a bit small but they are hand made (I think). These were the best price I could find.and they are well made.
The students enjoy playing with these. Will order more in the future. Fairly well constructed. Could use a book of directions though.
I was fascinated by this toy as a child, so got one for our son. He loved it, but is now 28. I made it into a sphere this AM and the cat played with it for 10-12 mins. The unpredictable roll seems to be the key.
