Both bottles are just as described and look beautiful. They’re also highly practical. I went for the large size—initially wondering if I’d been a bit too ambitious—but they’ve been filling up more and more with delicious kefir each day, so I suspect they won’t feel too big for much longer.

Super nice bottles and tools. Very useful. The blue lid on the second fermentation bottle is not able to screw very tight, but its still useable.
