Highlighter pens serve a completely different purpose to popular promotional ball pens which are used much more frequently. For this reason, many companies write them off as promotional gifts. They should think again! Promotional highlighters are a very popular gift because they are used so occasionally. They are a useful product for the receiver that takes a special place in their desk drawer. Due to the fact that highlighter pens are not used as often, they usually have a much longer writing life and are much more likely to remain in your customer’s possession longer.  Printed with your logo and details, they are a promotional tool that will continue selling for you for months.
