I had previously bought this brush in size 00 (at the time it was the only brush I could afford and it was the first time in my life I had splurged for a mop brush) but I loved it so much that I decided to get all of the sizes available in this range. This mop brush is great when you consider the price and the fact that it's synthetic - I did some comparison between multiple synthetic mop brushes available in australian art supply stores and this one benefits in being a tightly edited size range and in it's pricing while also being great to use. I love these brushes for gouache painting because it had enough "snapback" but it's still soft enough for watercolours even if it's not as fluffy and soft like a typical animal hair mop brush. This brush is perfect for when you want to make washes but also prioritize having some control and precision.
