Please note - Eraser contains traces of Isopropyl, please do not apply over any medium as it will remove it along with the paint.
If you can not remove your mistake with a wet cotton bud or a toothpick. Add a few drops of Eraser to a cotton tip and gently wipe over the area you need paint to be removed. This will help to remove paint. It may not always work and it will be impossible to remove any errors after 24 hours. Seal over area if you find it no longer takes paint.
IMPORTANT - DO NOT USE ERASER over and Gel or polyurethane products such as gloss, satin, 3D Dewy Skin or 3D Hair Effect, it will remove the medium as well as paint.
