Easy cleaning, leaving the solution in the bowl, suitable for bowl 14mm
Kinda works for cleaning? I mean I guess you can leave it to soak kinda but you either have to completely fill up the bowl and then its just a tip-over risk full of ISO alcohol, or you can just have the base filled but then it wont really soak. Ultimately it takes like 60 seconds to clean your herborizer bowl anyways. But I do like them as stands. I think if you put a bit of weight in them they would function great as stands for your bowls.
What they are really meant for is to insert the bowl in one end, fill with iso, plug the top of the bowl and shake. It will quickly clean the bowl this way and then just rinse with fresh water.
