Copic markers are not waterproof; they are alcohol-based and can be blended with each other or with certain solutions, but they are not designed to be waterproof once dry. While they are permanent on most surfaces, they can be reactivated with alcohol, so they may not be suitable for projects requiring true permanence or waterproofing. Always test on the intended surface for best results.
