I'd like it better if "vegetable fibre wads" were a special material, for the price they charge.
Look at the pictures they post of the bunch of them. They are nothing but Vellumoid gasket paper, bought at your local auto parts for about a buck a square foot. Granted, they are already punched out for them who are too lazy to tap a hammer to a punch.
"Vegetable fibre" is market speak for "paper"
Ah, well, do as you will.
Cheers,
