I switched to using a fountain pen with a bottle of ink 6 months ago to stop me using the plastic biros work provided. The problem I had was the standard highlighter pens made the ink run so I was looking for something to replace them then I found these. They work great, my ink doesn’t run and the colour is good they do the job I need them to do.
Totally the way forward and now I need to highlight everything. Will be buying them as Christmas presents for my work mates!!
