Review: Escrita super macia e agradável.
Review: I took advantage of the discount, received my order in a day and was happy to find the pens and ink are made in Japan. The box was a bit crunched up and I need to check all the pens to make sure the tips are all sealed and new, but the one I pulled out to test was sealed and wrote smoothly. No smears/smudges, clear black ink, well made and has a sturdy metal clip. I unscrewed the barrel to take a look inside. The ink barrel visually shows quite a bit of ink in the cartridge, so no short cuts there - should last awhile. Ink flow is clear and not blotchy. The muted colors are a nice touch and the tactile area where you hold the pen is smooth while providing grip. It's a well thought out and elegant design. I need to grab a few more boxes while the price is still at about $1/pen. I recommend this product wherever you can get it. Wish: I wish the ink color came in indigo.

A lovely looking pen, but very blotchy when writing in a Lechturn notebook. There are better options on the market.
