    • Great for pin cushions
The shells are ground very fine and can easily be put into the fabric with a funnel. The shells add a nice weight and feel to the cushion and keep pins nice and sharp as well. I plan to make more for my sewist friends and will continue to fill them with this product.

Great product, I used it right away for my pincushion drum. But the shipping was poor. It came inside the Amazon BAG not a box. The lid was cracked and 2 corners were dented. There was a small amount of spillage.
