Review on 2mm Fine Tip Yellow Chalk Pen for Writing, Drawing, Art Projects, and Decorations | Erasable Chalkboard Label Paint Pen by Cestari Kitchen by Angela Rodriguez

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 made; Only buy it for items you are sure are "non-porous". The pen writes beautifully, so if you know the surface you're using is fine, 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.
