This set includes five colors: Blue, Green, Pink, Purple, and Yellow. The ink features glitter blended with silver, adding a sparkling effect to your writing. These highlighters can be used to add dazzling highlights to books, notebooks, letters, and calendars. The ink produces shiny lines that create a rich, sparkling appearance. Unlike traditional ink, it does not require shaking before use and can be used freely. The pens are designed to resemble stylish cosmetics, with bodies that are as attractive and sparkly as the ink inside.
