I can't say enough good things about these weights. My least favourite part of fermenting has been improvising a way to keep the the veggies or fruit fully submerged and worrying about it. As soon as I got these I did up a batch up apple scrap vinegar and you just drop them in, no fiddling or worrying. It was so easy it was almost anticlimactic. Also The Apothecary shipped super fast so I was able to use them pretty quickly.
