Questions about this item

Does the 2-pack include only the two black cartridges or are any printhead cleaning tools or alignment sheets supplied?

The box contains the two remanufactured HP 21 black ink cartridges and no additional tools or alignment sheets.

Should I choose the 2-pack or look for a single cartridge if I only print occasionally?

The 2-pack gives two cartridges each rated at 190 pages, so it suits regular printing; a single cartridge is better for very light use.

What does the 190-page yield mean when I print mixed text and graphics on my DeskJet 335?

The 190-page figure is based on 5 % coverage; pages with heavy graphics or photos will use more ink and reduce the actual count.
