Designed specifically for The Mark Advanced Dark Spot Concentrate, The Key is a weighted gold squeeze key engineered to work seamlessly with its aluminum tube. Creates steady, even pressure as you roll, guiding the formula forward without bending, splitting, or creasing the tube. The result: smoother dispensing, less waste, and a more intentional way to use every last drop.
