Query: Very good

When I ordered these they were sold by Amazon (now they aren't so I just wanted to make the distinction). The box came with all 12 markers and when I received them I tested all the markers and they all worked perfectly. Since others have mentioned that their boxes came with less than 12 markers and that some of them didn't work, I checked all of mine right away. No problems at all, the price was great, and shipping was fast as usual.
