Review: Smooth Writing, Excellent Value Refills That Keep My Favourite Pen Happy - Pros • Smooth, consistent ink flow • Fine 0.5 mm tip writes neatly and clearly • No smudging or bleeding through paper • Excellent value for a 6-pack • Perfect way to keep a favourite pen in use Cons • Only compatible with pens that take this refill size I bought these refills quite a while ago for a pen I received on Mother’s Day. The pen itself isn’t expensive, but it has sentimental value, and replacing the ink rather than the pen was the obvious choice. Thankfully these refills fit perfectly and have kept it in regular use ever since. For anyone needing help ordering the correct refill; I uploaded a photo and desertcart did the rest. I’m quite fussy when it comes to pens. I have drawers full of them, yet only a couple actually make the “approved for writing” list. These refills have firmly earned their place. The 0.5 mm fine tip writes beautifully, with ink that flows smoothly and glides across the page without that scratchy feeling some pens have. There’s no bleeding through paper and no annoying smudging either, which makes them ideal for everyday writing, notes, or journaling. The last refill pack I bought (a pack of five) was back in May 2023, and it’s only now that I’m ordering more, which says a lot about how long they last. This time I’ve gone for blue just to mix things up a bit. Value Price-wise, these are a real bargain compared with many replacement refills out there. Some can be surprisingly expensive, especially if they come from well-known pen brands. These deliver the same smooth writing experience for far less money, proving you don’t always need to spend a fortune to get excellent performance. Verdict Reliable, smooth-writing refills that have kept my favourite sentimental pen going strong for years. Great performance, long-lasting, and excellent value. If your pen takes this style of refill, these are absolutely worth ordering. ⭐⭐⭐⭐⭐
Review: Rollerball refills - Thought I'd take a chance on these as I'd been struggling to find this type of refill locally. I feel that they're good value for money for what you get and the quality isn't too bad. The tips are a little scratchy when you're writing, but that was also the case with the official refill I originally had in my pen anyway. The ink is a nice shade of blue and overall I'm quite happy with them.
