Due to improvements to this kit, this kit will no longer accept the UNI-Ball® refill However, this kit does accept a premium Parker style gel refill that is available in all office supply stores and in our Supplies and Accessories Section.
This is a very unique addition to our Sierra Pen line. We have made this kit using a new clicker technology. The clicker is preassembled in the top. The new clicker gives a "softer click" that is also very positive and virtually trouble-free
