Review: Great pens! - Great value. Write beautifully. Very durable. Take a beating and keep working well. Nice fit in your hand. Perfect thickness!
Review: Best Blue Pens! - 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!!
