When my kids were toddlers, we used these in a cheap small swimming pool to make a ball pit.
Ball diameter is about 8cm.
They are fairly soft - a kid stepping on one would dent it (non permanently, you squash them back into shape), adult can dent by squeezing, a dog would bitw through easily.
The green ones are grassier color in reality (phone made them too emerald).
Let me know what's a good time for you to pick up. Best for me is 10-5pm weekdays (when kids away).
