I've got some black, some yellow, and some of the entirely plastic frames. The entirely plastic frames are absolute junk. I would have tossed them by now, but they are frames 4/5/6 in my hive that was queenless for a few weeks, so I figured best not to mess with it for a while. I'm going to try to go foundationless next nectar flow now that I've got ~30ish frames drawn out to use as guides.

Are you using small or medium boxes? Your frames looked pretty short from the pictures.
