I need an alternative to Newton sponges

[jesusmaryjosephandtheweedonkey]

I can't buy them anywhere and I'm down to my last one.
Anyone recommend anything similar or as good ?

Search for chiropody sponge rather than Newton sponge

I tried the Boots own brand chiropody sponge last week. I was devastated when they stopped Newtons but to be fair I think I prefer the Boots one

They've stopped Newtons!!! Disaster
