This pen refill is a direct replacement into the 207 Premier from Uniball, if you like the alpha-gels, the 207, Premier only, has the same grip with more cushion than the alpha-gel slim and a firmer grip than the fatter alpha-gel. The 207 Premier is a bit more attractive and comfortable to write with as compared to the fat and slim alpha-gels and accepts gel ink refills rather than ballpoint. I have yet to find a pen I enjoy taking notes with more than the 207 Premier, with these refills replacing those that come standard. My suggestion would be to order a few of these refills and have a 207 Premier waiting for a transplant by the time your order comes in the mail. I promise you will not be dissapointed if you've been searching for a comfortable pen that can lay down a very fine line and still handle a days worth of note-taking without skipping.

Very nice to finally get these hard-to-find refills. They fit the pen perfectly and I can't find them anywhere else. Thank you!
