FFS - PrismIQ Keyboards

I am starting to clean out stuff, and one of the things I don't need are these new PrismIQ IR keyboards. Apparently they were originally used with some multimedia stuff in the early 2000s. Because I am just trying to get rid of this stuff, I am only offering them in cases (boxes) of 10 keyboards. These use IR to connect to the device and have no other connectors. The keyboards are membrane type with the main chip inside being a Winbond W78le812-24. Power is supplied by four AA batteries. The cases (10 keyboards) are 20 pounds with a size of 18"x18"x10", and I am in Santa Barbara, CA. Unfortunately, I am unlikely to run out since I have some 40+ cases of them. I generally ship USPS Priority but can ship UPS if necessary. And again, they are free for the cost of shipping.
