Natural Sea Sponge for shower or bath

Natural Sea Sponge I have what are called wools, grass, and yellows
these sponges will last years but theres a catch you must use only soaps
made with lye and oils called saponification  cleansing products sold  in grocery stores
have chemicals that mimic the properties of hand made soaps. these chemicals cannot be
rinsed from the sponge and make the surface of your sponge slimy feeling ewww so enjoy this sponge for years as i have just uae handmade soap when you do
