One more "Ditto" on the Streamline. I sell a boatload of them. They come in two flavors, flat top and round top. Both work well for me. I charge an extra buck for the round ones, because the kit is a touch more. I started with 5 wood and 15 acrylics on the table. I still have 4 wooden ones left, and I am on my fifth batch of acrylics! One caveat with the Streamline (And the Olympia, perfect fit and several other pens which have a lot of taper) If you are using a slightly transluscent acrylic, it will show a color difference between the center, and the ends ofthe pen. It is important to paint the holes and tubes well, and also to match the paint to the acrylic. A little caution will make for a great looking pen. The streamline has become my most popular pen with the ladies.
