Love these pens. Helps make my handwriting legible again! And my grandkids -- high school and college love them.The younger grandkids use them for sketching. Great product!Smooth flow. Ink dries instantly.These pens glide across the paper like a warm knife through butter!My wife had one of these as her favourite when I met her 10 years ago, and she was very disappointed when it finally gave up.Labelling had changed slightly over the decade, but I managed to find this renamed as the 'Worker' version.Gave her quite a pleasant surprise to get her a box of 10 of them - pure luxury.Fairly long lasting for a gel pen, and writes outstandingly. Everyone who gets to borrow one of mine comments on it and wants to keep it. If you don't like the idea of capping and uncapping there is a retractable version, if not more than one. I have been using these for a number of years now and would say that if you are not going to write with a fountain pen, then these should really be your next choice.Bought these for their feel in my hand, the pressure on paper to write, the quality of line they produce when writing. As I handwrite for hours a day I need something that doesn't unduly tire my fingers and wrist when working. These are beautifully balanced in my hand. The aesthetics of the design are pretty good too. I simply enjoy writing with them. A few from the pack were snaffled by my son. They've replaced his favourite pen, which has saved a bundle on refills there too. Quality pen for the price.These pens are great. 0.3mm is definitely a better size.I just wish the ink didn't come off and get smudged so easily and make a mess of your hands.Once the ink is on your hands it takes a lot of persuasion and a coupe of days to come off.These pens are amazing and I would believe they would last forever if my dog hadnt developed a taste for them and no other pen!! Having to buy them 10 at a time as I love them that much. I DO try and keep them away from the dog but he is tenacious when it comes to these pens!!
