These bulk rolls of the Dymo large shipping labels have been developed for the customer who is sending higher volumes of parcels and packets. Not only with they save time as you won't need to change rolls so often, these jumbo packs will save you money too, as this is a more cost effective way to buy than the standard 99014 rolls of labels.
