Thank you for viewing. I am selling the above cartridge because I accidentally purchased it and cannot return it as it was purchased online. I opened the box once, but I have not touched the contents. The contents are new and unused, but please refrain from purchasing if you are concerned as it has been stored at home for a while. Instant purchase is OK. I will also consider price negotiations within a reasonable range. Please feel free to contact me.
