Sedulus 高級平頭畫筆，銀色金屬箍，18mm

Finally, a flat brush that actually holds its shape even after multiple cleanings—the 18mm width is perfect for covering large areas in my wet-on-wet landscapes. The handle feels solidly attached to the ferrule, no wobbling at all.

The 18mm flat holds a surprising amount of paint for wet-on-wet work, and the seamless ferrule feels really solid in my hand. I've had cheaper brushes come apart after a few sessions, but this one seems built to last.

The ferrule on this flat brush feels rock solid—I’ve had other brushes loosen up after a few uses, but this one holds the bristles tightly. It laid down a smooth, even 18mm wash of paint on my canvas without any stray hairs. Exactly what I needed for wet-on-wet work.
