The directions say to use three stones per glass

Youll need about 34 per glass so if you might be entertaining more than 3 people including yourself it might be worth it to you too pick up 2 sets

Upon arrival and opening the box 9 grey little stones yes statements made before with rounded edges snug laying one next to each other and a black velvet back was there in front of me

No marks no scratches no anything

I would not suggest putting these into anything that fizzes my thought would be that the cube would break down
