Bought this for my 10 and 6 year old grandchildren. Extremely disappointed in the sizes of most of the “pebbles” because that’s all they were. The largest piece was the size of a dime! Basically someone’s junk!! Won’t buy anything on here again. Had also bought Dino eggs to open, another waste of money. I was hoping to use them as educational fun with the kids,😠

The photo is a little misleading. You do receive some neat stones however they are very small pieces and many are just crushed that make a mess. The chart is nice and bags are great to store them in. I would not buy again though for the price.
