As someone who paints almost daily, I can confidently say the Da Vinci CosmoTop Spin Brush (size 20) has become my secret weapon. The first time I dipped it in water, I was shocked by how much pigment it held – like a thirsty camel at an oasis! The unique oval shape lets me switch between broad washes and fine lines just by twisting my wrist.

What really won me over was its durability. After 6 months of aggressive use (I paint landscapes with lots of scrubbing), the bristles still snap back perfectly. Unlike cheaper synthetics that go limp after a few washes, this brush maintains its springiness like it's brand new.

The red handle isn't just pretty – it's ergonomically balanced for those marathon painting sessions. I've accidentally left it sitting in water overnight (oops!), yet it never developed that dreaded 'hook' at the tip like other brushes do.

Is it pricey? Sure. But when you consider I haven't needed to replace it after hundreds of paintings, it's actually saved me money in the long run. Pro tip: The size 20 is perfect for medium-sized works – big enough for washes but precise enough for details when used sideways.
