This is a stainless steel set with enough weight to hold the brushes even when most of the handles are out. Said differently, it helps keep the brush hairs under water without deteriorating the handle. The inner crevasse helps to remove excess paint from the brush and cleans it better; the perforated base has the same effect.
The main downside is that this medium-sized container is actually quite small. See my photos against one of the average metallic glasses I use for painting. I would be happy to purchase a larger version for my long bulky brushes. For the rest, this one is perfect for those brushes that I use during art journaling or sketching, or for short-handle wide mottlers.
It cleans well and easily under running water.
