1mm Waterproof Chalk Pen
- Waterproof chalk pens won't rub off when in contact with moisture - like condensation from a drinking glass, or rain!.
- Dust-free liquid chalk, for the look of chalk without the smudges or mess.
- Write on any non-porous surface including chalk labels, mirrors & glass, and metal. Not recommended for chalk paint.
- To remove, simply spray with an ammonia based cleaner like Windex.
- To use: shake pen upright for 10 seconds, remove cap and press the tip onto paper or label until ink comes down - this may take several seconds.
