This is the most common ballpoint refill shape in the world (Parker style). Fits many many brands including all Franklin-Christoph and Piper standard ballpoints. [3.88" long] - The Piper Ultra-Glide is so smooth you might think it is a rollerball, but with the long lasting, clean writing of a ballpoint.
Note - this style refill has been replaced by our new Franklin-Christoph Softline 1000, and the price has been reduced to closeout remaining inventory of the blue Ultra-Glide refills.
Both refills are very smooth, the only difference being the Ultra-Glide is a little "wetter."
