I work at a laundry for hotel linens.
I was not satisfied.
I wanted a marker to write quickly on the packages, but its ink takes a long time to dry, resulting in me getting stained, and also the marker has a ball inside that you have to shake every so often for the ink to come out.
I will not buy it again, I will prefer something faster and that dries in a short time.

They were used for painting on outdoor benches painted with wood stain. The result was perfect. It dries very quickly and for now it seems like it will last for years.
