Strong enough for several uses.
I use this to brush/clean my cat's teeth and they work better than I expected, I can use the same sponge 5 to 7 times without having it break, considering how sharp cat's teeth are, my cat does not resist, so is an easy process, I don't need to maneuver the sponge in a forceful way at all, when it breaks, just cracks, so far I haven't had a sponge breaking into pieces, I use it moist with the teeth cleaning spray they sell for pets, I have never used it dry.
