These are Jetstream replacement ink refills. I removed these from a commercially available 4-in-1 pen body and replaced them with other refills, so I have kept these in storage without using them. Although they are unused, most of them do not have their outer packaging, so I have marked the product condition as "Like New". Packaged: Black 0.5mm - 2 refills Loose: Black 0.5mm - 2 refills Red 0.5mm - 5 refills Blue 0.5mm - 6 refills Green 0.5mm - 1 refill Green 0.7mm - 2 refills
