We buy the markers for the men to use out in the field when packing a customer's shipment of household goods at the origin address. They mark on each carton the room the carton was packed from and the contents of the carton. It is important to have permanent BLACK BOLD markings on all of the cartons so anyone who delivers the shipmant at the destination address will know what room to put the carton in.
Product used by multi individuals to label boxes and bags in a food pantry location. Work is at a fairly rapid pace. Sticking lids an smearing ink slow us down. But the dark color is clearly visible and once ink dries it stays in place. We use this in a charity situation and all funding comes through donations so price is a big factor when we look for supplies.
Very easy to use doesn't dry after just a few uses as other brands do(or they are already dry out of the box and hard to write with);marks everything well on different types of paper;covers text well if you cover passages to eliminate them; doesn't produce toxic fumes that make you nauseous.
