I’ve been using Pokka pens for several years and wouldn’t leave home without at least one! They slip right into my pocket and/or stow away in my EDC pouch without taking up valuable space. They NEVER leak, and the bright colors make them easy to see in my sling. I have used other, more expensive pocket pens, but there’s virtually no difference in performance but a big difference in price. I’ve had a lot of people ask about my Pokkas, and I always give them a great recommendation.
