BrilloSteel Wool Soap Pads 794628302188 Original Scent (Red), 30-Count Jumbo Pack

This particular description says "Jumbo." I would like to know the dimensions of the pads themselves if possible.

which is difference in price between Brillo 30ct and 18ct?

Can I use these to remove hard water deposits on my plastic juicer parts?

I have been trying to purchase this item for over a month now i believe and it keeps saying temporarily out of stock. Are you getting more?
