I have a large collection of "historic family photos" which needed proper identification. I tried one of the "photos pens" from Amazon but it leaked through the paper and ruined a photo. This is not only permanent but looks professional. The cost is secondary here to the functionality. PS - By adjusting the margin setting, printing on the middle font size, and using the return key to create a two line label, you can save valuable tape. Using the "memory" function you can avoid typing common entries too many times.
