The ballpoint line contains the famous oil based, water and light resistant Jetstream ink that writes incredibly smooth. The gel ink line contains the popular Signo ink that is the same as that in the popular selling Uni-ball Signo line. The mechanical pencil is pre-filled with Uni-ball NanoDia Low-Wear pencil leads, which are infused with nano-diamond pieces to create an unusually strong and high-quality lead. The combination of all the above allows you to create a multi-pen that has all the best Uni-ball qualities in one single instrument. In addition, the system is eco-friendly since you can refill it again and again.
To get started with or refill your Uni-ball Style Fit multi pen, first, take the pen body apart by unscrewing the grip area away from the main barrel.
If you look inside the barrel you will see different circular holders for each component tube. Press the back of these components into each of these holders.
It helps to hold the tab which corresponds to the space you are installing the refill in, as this can add some extra stability to the process.
Once you have filled all the available spaces, screw the pen body back together and you're ready to use your Style Fit multi pen!
(A good thing to know is that you can refill a lot of the multi pens we carry in similar fashion.)
