I have 20 sets of Allen hex key sets available NSN-5120-00-935-4641. They are 20 key sets but these sets do not include the 3 smallest sizes: .028, .035 & .050. The sizes range from 1/16 to 3/4. Some keys may have slight surface rust from storage but the keys look to be mostly unused. The cases are in vary in condition and none are perfect. Three of the cases are the blue pouch style and the rest are the green sleeved cases. These are 45.00 shipped Priority Mail. I am in Colorado Springs so if you are close you can pick them up. Please feel free to PM if you have any questions.
