The color is part of Mill Stream's pinch-on, closed cell foam indicators, so it will not peel, fade or run like the color of other similar indicators. The closed cell foam won't get waterlogged like yarn indicators. The agressive, waterproof adhesive backing will stay put until YOU decide to remove it - and will leave minimal residue when it is removed. Available in three colors. Each sheet contains 32 punch-out indicators in two different sizes.
