One Clip for storing cartridges.

You need to protect the printhead with a piece of Saran Wrap or Scotch Blue Tape.  The Blue Tape is a specially made tape and expensive. If you do not have Blue Tape, use a piece of Saran wrap between the printhead and the foam on this storage clip.  Do not put the printhead directly on the foam.

This is NOT a priming clip.

The package includes one Storage Clip.  It works on both black and color-integrated cartridges.  If you have a color and a black cartridge, you will need to order two.
