Holds in water well, but was a little thick for my liking. Nevertheless I will still use it because of its absorb-ability. 

Sponges are ubiquitous in pottery…and, especially with throwing, how can they really improve it so much that it will be a game-changer?
Well… they did. The tough sponge is a game-changer! I throw porcelain and it is a thirsty clay but equally collapses at the first hint at too much water. This sponge held on to just that right amount where it didn’t dry out and yet didn’t saturate my clay!! So worth it!!
