Best Blue Pens!

MK—February 5, 2026✓ Verified purchase

I’ve always been picky on pens and pencils and Pentel quality does not disappoint. I tried the energel RTX blue 0.7 ink first in a different multi-color set. I usually prefer unique colors (absolutely LOVE the navy-blue and turquoise energels) but something about this regular, “boring” blue color struck me. It was vibrant without being too bright and the perfect shade. I like signing documents in blue (old habit from legal work days) so bought a whole pack of 12. As all pentel energels, ink flow is super smooth and I love how the pen feels on paper. They may not be the cheapest pens out there but quality makes it definitely worth it. These will probably last me a while!! Read more

Best TRUE PINK gel pen that dries quickly

Raul—January 10, 2026✓ Verified purchase

best Pink Gel Pen ever- Take it from the guy who has 2 to 3 hundred pens at his disposal at any given time. Pen Tel 0.7 Gel pens are the best- especially the colors. This Pink is the best. Came in a multipack and I had to buy a whole box. My Fav's are the Dark Blue, Dark Red, Black and this pink. I have perhaps 20 types of Pink pens and this by far is the best example of what a pink gel pen color should be - 5 stars Read more

The Only Pens I Write With....

Peg Leighton—February 12, 2026✓ Verified purchase

I love these pens, and have been using them for years. Occasionly, I buy the refills to save a few dollars, but generally just buy a new pack. They're the only pens I write with and my journal is full of Purple writing... lol They write very smooth, don't leak, or smudge, and are very comfortable to hold. Read more

Nice and Reliable

M Watson—February 13, 2026✓ Verified purchase

These are very nice pens. I generally use the Pentel 0.5 and 0.7, but I've switched to these pens for a bit more money. They have never left ink blobs and are comfortable to hold due to the softer material at the lower end. Read more

★★★★☆

Love these pens - use them all the time

IrishSa—May 31, 2024✓ Verified purchase

Love these purple pens. This is my second or third box of them. The ink flows well and they last a long time. I will be honest that every once in a while I've gotten a bad pen that does not flow well. But other than that they are fairly comfortable to hold and write with. Read more

Perfect for Sudoku Addicts

Michele A.—March 28, 2025✓ Verified purchase

I happen to be addicted to Ultimate Killer Sudoku puzzles and will spend 3-4 hours at a time working in a book. Needless to say, my writing utensil must be perfection. I need a very comfortable grip on a smooth-flowing pen, and I don't want blotches or smears in the number grids. When I first got serious about UKSudoku, I experimented with many different types/styles/colors of pens before finding Pentel Energel .07 in black ink. This specific pen facilitates ease of writing, clean print, and it's easy on the eyes. It's also long lasting. I'd been using this pen exclusively for years until just recently when I also tried the Pentel Energel .07 with the removable cap. Though the ink seems to last longer in the pen with the cap, this retractable model is still more comfortable for ongoing use. Read more
