Spellbinders mini brushes are designed for detailed work, coming in a set of three sizes (3/8 inch, 3/16 inch, and 1/8 inch) with straight brush heads for even application. They are ideal for tasks like detailed inking, working with intricate stencils, or applying color to small die-cut shapes. The white color of the brushes makes it easy to distinguish ink colors, and their straight head design promotes consistent color application.
