Prismacolor markers

I have a rainbow set of 12 never used and a set of twelve cool grey colors! The cool grey set comes with 3 blacks. I also have an extra black in chisel tip and brush tip. There is also a colorless blender. These are all prismacolor premier markets and both at are chisel tip double sided! They also come with two bolder that have extra room for more markers! I am willing to negotiate a price but for 27 marked and the cases which I paid over 70 for total I am asking for thirty for everything!
