These stones were found on the shore of the Baltic Sea. It is natural pebbles, anyone can come up how to use for them himself.
Dimensions of stones can be seen in the photographs.
They can be used for playing with your child: they can be laid out any pattern or any figures, use them as counting sticks. Of them can make a mosaic. They can be sprinkled on the earth in the pots with flowers or decorate the bottom of a vase of flowers.
Wet stones have a more vivid color. REMEMBER, each computer monitor is different and colors can appear slightly different than the actual item. I do edit EVERY photo so they appear as close to actual as possible.
