Dritz Mark-B-Gone White Water Vanishing Pen
This pen uses a water soluble white ink. For best results, use on washable fabrics. This is not recommended fo dry clean only fabrics.
Always test marking pen on the fabric you are using to be sure marks will completely disappear. Some fibre contents, fabric finishes or dyes )red and pink in particular) may not be suitable for use with this pen. Do not iron over marks or launder before completely removing marks with plain water.
It is always a good idea to test ANY marking pen, no matter how good it is or how much you trust it, on a spare piece of fabric before you mark your project, just to be sure.
