How does the 8x8x4 have the same surface area as the 8x8x1? I would think out would have at least twice the surface area. What gives? Lol

That chart shows how many square feet of surface area are in a cubic foot of the material. For individual pieces, the surface area of an 8x8x1 is 5750 feet squared and an 8x8x4 is 23,000.
Just got some of the spheres yesterday and they didn't appear to be very fragile at all. There was a small amount of dust in the bottom of the bag, but the spheres were fine. A quick rinse and they were clean and ready to use.
Yea, they really are pretty sturdy. Thanks a bunch for your order
