The Pentel Energel Tradio Liquid Gel Pens have been around for awhile but only in the white and black body colors. I have not been a big fan because I perfer the larger Tradio pens. They also can be set up to use the Energel refills. I also was not a big fan of the hard smooth plastic. The new colors have me using them again. I just like colors.
Blue, orange, green, purple and the yellow are very bright and are just fun to use. Energel refills are used in many of the Pentel pens. I have only found these on EBay. Get yourself a set of five and add them to your collection.
