About Builder One

Build up the intensity of your eye look with this handcrafted flat eye shadow brush. Designed for effortless defining, smudging, and layering, Builder One makes it easy to pack on pigment exactly where you want. Plush saikoho goat bristles pick up and lay down any type of eye shadow—even tricky finishes like glitter or metallic.

“This is the brush of my dreams—I love shimmers and metallics but only when I can control the placement and application. The shape works magic with difficult textures.” — Sonia G.

Why It’s Special
  • Builder One’s flat silhouette picks up eye shadow and deposits it exactly where you want it, allowing you to shade, smudge, and define without messy fallout
  • Each brush is handbound by master artisans in Japan using traditional brushmaking techniques for unparalleled performance and craftsmanship
  • The sturdy handle is made from dense, sustainably harvested maple wood and coated with four layers of pigment and lacquer for a rich, dimensional finish
How to Use

Pick up product with the flat side of the brush using short, zig-zag strokes. Tap off any excess, and then use a similar motion to place the color on the lid. Use the tip to define or smudge the lashline, or to extend the pigment into a wing.
