I was hoping to use them for my bullet journal and so many pens bleed through even though the paper is not thin.** A: They haven't bled through on my A4 lined sheets of paper. However, in my nu:era book (where the pages are thicker) they haven't bled through but they do show more. I think the paper must be more porous in the book. If your journal is similar they may also bleed through. **Q: Hi can you confirm the colours in this pack? The doesn’t look like it’s what’s listed!** A: It's the 5 tropical colours, exactly as shown in the first picture. As seen. And as listed. To be certain, email the seller. In my Amazon experience, they respond quickly. **Q: What colours are in the pack ??** A: There’s purple, pink, orange, green and blue. The ink that comes out is pretty much the same colour as you can see on the tip of the pen. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent pens a must buy !! *by E***R on 27 July 2025* Love these pens as the colour is so vibrant and the writing is ace with these pens!!
