Kai Lun Qu x Trekell Black Opal Brush Set

Created in collaboration with Trekell Pro Team artist Kai Lun Qu, the Kai Lun Qu x Trekell Black Opal Brush Set features his signature selection of six long flat brushes, designed for bold, intentional strokes, precise edges, and controlled paint application.

Built with alla prima oil painting in mind, these brushes provide the precision, spring, and control needed for expressive mark-making and confident brushwork. They are also well suited for acrylic painting, making this a versatile set for artists who value responsiveness and consistency.

We’ve taken our popular Opal line and given it a sleek, distinctive finish:

• Black synthetic filaments for responsive, controlled brushwork

• Black ferrules for a sleek, cohesive look

• Long dark red handles for comfortable grip and extended reach

The result is a limited-edition brush set that combines Kai’s preferred shapes with a striking new look.

2 x Size 0 Long Flat – Fine details, controlled edges, and precise strokes
2 x Size 2 Long Flat – Versatile mark-making, edges, and controlled paint application
