"A portable, practical solution for artists on the move, Raphaël Soft Aqua Travel Brushes feature a compact shape and innovative, wavy synthetic fibers for unsurpassed fluid capacity with watercolors, ink, gouache, and more. Offering double the water-carrying capacity of conventional brushes, the undulating shape of the fibers creates a reservoir for water molecules—ensuring even, flowing color from base to tip. Protective caps cover the brush head during travel. When you’re ready to paint, the cap fits securely on the end of the brush to lengthen the handle." -Blick
