Our liquid chalk markers come in two types: wet-erase and dry-erase. In general, you can wipe them off easily from a non-porous surface using a dry tissue or a damp cloth. While the markers themselves are not waterproof, they have excellent fade resistance when used outdoors and are not easily affected by environmental conditions.

Even after opening, please seal the cap tightly. Liquid chalk ink with a protected cap typically does not dry out easily. However, to prolong its lifespan, avoid prolonged exposure to high temperatures or direct sunlight. It is recommended to use it within 6-12 months after opening to ensure optimal performance.

Under normal use, the tip is durable and resistant to wear. If the marker hasn’t been used for a long time, the ink may dry up at the nib, causing clogging. Simply press the nib a few times or rinse with water to restore smooth ink flow.
