Pentel - Aquash Water Brush

Aquash Water Brush

Blend watercolors anywhere with a refillable brush that controls water flow

Watercolor sketching on location means carrying water containers, managing spills, and constantly dipping brushes. Aquash brushes eliminate all of that. Fill the barrel once, and you control water flow through a responsive squeeze, more pressure for saturated washes, light touch for subtle blending. The self-contained system lets you activate watercolor pencils, blend pan colors, or carry diluted ink for immediate application wherever you work.

Pentel's valve design delivers consistent flow without flooding, while the durable nylon tip maintains its point through extended sessions. The flattened barrel prevents rolling on tilted surfaces and provides ergonomic grip during detailed work. Choose fine-point for precision details, medium or large for broader coverage, or flat for controlled washes and edge work. The four-brush set covers the essential range for field sketching.

Whether you're capturing quick studies in a café or spending hours on a trail, these brushes perform reliably without the infrastructure of studio painting. Refill from any clean water source, rinse the tip, and continue working. That simplicity matters when you're focused on capturing light and atmosphere rather than managing equipment.
