Use on projects to be completed within 24 hours. For best results use on washable fabric. Store pen with cap on and point facing downwards. Always test marking pen on fabric you are using to be sure marks will completely disappear. Some fiber contents, fabric finishes or dyes (red and pink in particular) may not be suitable for use with this pen.
Mark fabric lightly.
Disappearing ink normally disappears in 24 - 72 hours (Humidity and penetration of ink can alter timing).
