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. ## Frequently Bought Together - Uni-Ball EYE UB-157 Fine Liquid Ink Rollerball Pen - Tropical Set - Pack of 5 - Uni-Ball EYE UB-157 Rollerball Pen 0.7mm Ball [Pack of 10] One of each colour - uni-ball Vision Stick Roller Ball Pens, Fine Point, Black Ink, Pack of 4 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/48366298-eye-ub-157e-fine-liquid-ink-rollerball-pen-tropical-set](https://www.desertcart.jp/products/48366298-eye-ub-157e-fine-liquid-ink-rollerball-pen-tropical-set) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-01*
