I've looked at these over the years and never bought any. I have a couple jobs that I want to try some on so I ordered a set of 6, 2 in each size. When I went to the mailbox, I saw two separate boxes but didn't think anything of it. Opened them up and its 2 sets of 6, one in each box. Figured I must have ordered 2 by mistake so I went onto the computer and checked the invoice. I had only ordered one set and billed for one set. Maybe Bezos sent me a Christmas present.
