Those are used and some of them are a bit dirty (been used in a garage), and some are nice and clean. They should all work fine. I think I have not tested the only one (the smallest cheapest one). The orange one is clean and works great for sure. Selling as a bundle as is.

The orange box you see on the picture is still in like new condition and was vought for $40. So, this one alone is worth more than the price I'm asking for the entire bundle.
