NEVER use any chalk markers on chalkboard paint or low-quality porous chalkboards. Test in a corner first.
Use new upgraded ink that brings more vivid colors. All colors are extremely pigmented, vibrant, and long lasting!
Liquid chalk markers can be erased easily by wiping the area with a damp cloth or paper towel.(ERASABLE ON NON-POROUS SURFACE ONLY!)
Always thoroughly shake your marker if you haven't used it recently (with the cap on) to make sure the powder and liquid are well mixed. This ensures a smooth flow and bright colors. If it's runny, shake a little more.
