Highlighters are water-based ink pens used to emphasize key text in books or documents by adding a transparent colour, making the selected text stand out without covering it. Businesses procure custom highlighters at wholesale prices for branding and marketing purposes. These pens are particularly popular among students and office workers for keeping track of important information and streamlining their learning process. To enhance the success of your business promotional campaign, you can procure promotional highlighters in bulk from PapaChina.
