I love these highlighters! While some of the colours are a little dark for highlighting, I knew that already, so I was expecting it. The colours are beautiful, they don’t smudge printer ink at all (I have had smudging will gel ink pens, but I didn’t allow it to dry before I highlighted the writing, so probably my fault). I have a heavy hand, but none of the nibs have bent. I also get very little/no pooling of ink from where I first touch the pen to the paper. I can get some ghosting (I mostly highlight typed notes on standard 80gsm printer paper), especially with darker colours, but it’s mostly unnoticeable, especially when the paper is flat. I’ve had no bleed through with any colours. Finally, my order was processed and dispatched quickly, and my products arrived to me quickly as well.
