Write on glass or chalkboards with a chalk pen or chalk marker, as this type of pen is also called. The color becomes beautifully opaque and rich. The white and yellow pens are perfect against a dark background. The paint can be erased with a little wet paper towel or a damp cloth. Once the chalk paint has dried, it can withstand water splashes. The paint also won't smudge if, for example, you rest your hand on the text when adding something.
Chalk pens can be used on all non-porous materials.
This chalk pen, Chalk marker PWE-3MS, from the manufacturer Uni, has a round tip measuring 0.9-1.3 mm depending on the angle you write with.
When the pen is new, you must shake it and press the tip against a hard surface a number of times so that the ink flows. Store the pen horizontally.
Cleaning tips
If your notes with a chalk pen have remained untouched for a long time, it can be difficult to remove the paint by just rubbing with a damp cloth/paper. Mix a little baking soda in water and use it to clean your chalkboard or labels. One teaspoon of baking soda is enough for one deciliter of water. If the paint still doesn't come off, increase the dose of baking soda.
