Konjac Sponge Set — Made from a
root vegetable, this sponge gently cleanses and exfoliates delicate skin, making it perfect for
use on the face or with babies.
I've never tried to exchange them, but I found this at Cooking.stackexchange.com: «Glucomanan (
konjac root) is suitable for making syrups, but it will have a different consistency than xanthan (some people
use them completely interchangeably in puddings and sauces), though it is completely interchangeable with xanthan gum / guar gum in gluten free baking.»
