I see A LOT of people are having the same problem.** A: I've had the exact same issue. Pen had a crack just above the grip; the pen doesn't stay together. Have to keep finding the pieces after it goes flying everywhere. I've bought refills already but I won't be buying anymore after I'm done with the refills. **Q: Are these the cheaper ones made in Mexico or the high quality ones that are made in Japan?** A: The ones I received (May 2020) were made in Mexico. Definitely cheaply made - even the box was falling apart when I received them. One barrel was already cracked. We could attribute that to bad packaging, but my "old favorite", which was made in Japan, would NOT have cracked in shipping. I also noticed right away that the barrel color was different. I've used the ones made in Japan for 20+ years and they were - emphasis on were - my favorite pen. **Q: The title/description says .5 mm needle tip, but the picture shows the larger medium tip. Which is correct?** A: There are 3 options of tip size on the one page- .5mm .7mm and 1mm. Not all sizes are available in all color options and not all color and size combinations are available in the multiple pack quantity options. Whichever size you choose in whichever color opted for will arrive in the pack quantity selected despite what the generic picture depicts as it is only 1 of the many options offered. **Q: Is the ink waterproof? Can I use highlighters without smear?** A: The ink is waterproof and you can use a highlighter - just make sure the ink is dry before highlighting. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by M***M on December 27, 2025* ### ⭐⭐⭐⭐⭐ Review *by J***N on August 30, 2017* ### ⭐⭐⭐⭐⭐ Review *by B***V on February 16, 2026* ## Frequently Bought Together - Pentel EnerGel RTX Retractable Liquid Gel Pen, (0.5mm), Fine Line, Needle Tip, Black Ink, Pack of 3 (BLN75BP3A) - Pentel EnerGel RTX Retractable Liquid Gel Pen, (0.7mm), Medium Line, Metal Tip, Black Ink, Pack of 2 (BL77BP2A) - Pentel EnerGel Pearl RTX Retractable Liquid Gel Pen, (0.7mm), Medium Line, Needle Tip, Black Ink, Pack of 2 (BLN77WBP2A) --- ## 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.com.kw/products/8542637-energel-rtx-retractable-liquid-gel-pen-0-5mm-fine-line](https://www.desertcart.com.kw/products/8542637-energel-rtx-retractable-liquid-gel-pen-0-5mm-fine-line) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-20*
