This is THICK cartridge, not THIN, for your information. I just called HP and cleared up a few things if anyone is interested. I have an HP Photosmart 7525. I ordered this original cartridge that fits the thicker cartridge. When I called HP they told me if you need a thinner black cartridge it says photo ink. Photo Ink Model Number: CB317WN#140 - if you want to enter it on Amazon website or HP Ink website. I told them they really need to sort this out for customers so we don't all get stuck with the wrong cartridge size. I know I will eventually be able to use it, but I needed a thinner cartridge (photo ink) and ordered this genuine ink cartridge. I hope this information helps others!
