These were bought for Christmas so my kids haven’t played with them yet, but I did open them up to get a good look at them. They are a good size so I’m not concerned about letting my youngest play with them. There’s no way she could fit a full one in her mouth. The colors are amazing, and it really is a true matte which is exactly what I was looking for. I tested them out by stacking them, and they stack in such a fun and unique way. You can make arches with them, and the “rocks” balance very well while stacking. I know my kids are definitely going to love these and get a lot of play out of them.
