This Color Magnet Dye Kit includes base color dyes, a Color Magnet pen, stencil sheets, rubber bands and instructions. Customize your garments with this kit using the Color Magnet pen and stencils and allow to dry. Next, simply wash the garment along with the dissolvable, washer-safe dye packet in your washing machine. This product magically attracts more dye, resulting in a darker shade where Color Magnet is applied.
