KEY LEAVES® is a Seattle-based family business specializing in wind instrument care products that leave keys open to dry. Key Leaves was founded by Rulon Brown, a professional saxophone player and music teacher who grew up fixing horns at his local music store. Like all saxophonists, Rulon ran into the problem of sticky key pads that cause playing malfunction and costly repair. So he created Key Leaves natural-care products to eliminate sticky keys and help musicians sound their best.

Since launching in 2018, Key Leaves has won praise from world-class players and repair techs, and critical acclaim beyond any wind instrument accessory from the last 75 years.

Rulon Brown began as a self-taught designer making products by hand in his garage. Building on the success of Key Leaves, Rulon grew the patent and product portfolio to include GapCap® end caps, Vent Vine™ key props, Spit Sponge™ pad dryers, and now the RULON product line.

In winter 2022 Rulon Brown launched RULON, a line of musical instrument products to give brasswind and woodwind players luxurious comfort and even higher performance. RULON products include tools for music education, ergonomic comfort gear, and instrument cleaning cloths featuring limited-edition fashion prints. RULON designs draw inspiration from elite sport and modern design, yet soulful craft is the beating heart of each RULON design.

When a RULON product helps a child with small hands start learning saxophone, a creative soul grabs hold of musical adventure. When our compact screwdriver gives an instrument a quick fix before showtime, the artist takes the stage with confidence. When our ergonomic designs help a musician play with less pain, their music can sing. RULON helps you get comfortable and play. So we keep drafting, sculpting, testing, chopping, blending, and crafting our way toward radically useful music gear so you make your best music and look great doing it.
