Review on 🖌️ Bold White Liquid Chalk Marker Set - 2mm Fine Tip for Writing and Drawing on Chalkboard Labels - Erasable Chalk Paint Pen - Ideal for Organizing, Parties, Spices, Weddings, Crafts - 2 Pack by Cestari by Barbara Simmons

Attention! This pen is NOT suitable for regular blackboards. I'm not sure why the sellers aren't more specific about this. I used this on a Pottery Barn chalkboard tile and it doesn't wash off completely. If you read the product description it says it will "rub off" on non-porous surfaces. Obviously they expect the average consumer to know that regular slate is porous. Well I guess I've been updated now. It ruined my board. Don't make the same mistake I did; Only buy it for items that you are sure are "non-porous". The pen writes beautifully, so if you know it's fine on the surface you're using, you'll probably be happy. It's a very short and thin handle, I don't know how long it will last and might not be easy to hold well in large hands. It was difficult for me to hold and I have small hands.
