At least 50% were smashed  more or less just gravel  usable for what I'm doing with it but I would think most ppl would not be happy with it

    Nature's Ocean No.10 Hawaiian Puka Shell for Aquarium, 15-Pound (SHAM)
  

*by S***R on Reviewed in the United States 🇺🇸 on August 8, 2014*

Nature's Ocean No.10 Hawaiian Puka Shell for Aquarium, 15-PoundLet me say this product is a sham! Puka shells as the description portrays or shells period virtually non existent and is mostly crushed coral, none of it is any more than 3.5mm. I purchased this believing it was PUKA SHELL and not crushed coral…..I also purchase Nature’s Ocean No.5 Taiwan Coral Aquarium Gravel 20 pounds (Grain size: 6.0 -8.0mm) no more than 3.5mm and it is exactly the same as No. 10 Hawaii Puka Shell, they are identical. Both product description and photos are deceptive. I can not use this as intended, I’ll be returning this and the other as well.
