SlantyChris,
Thanks much for the T206 frame. Put one of my cards in it and I really like the form/fit/function of this version. The width fits my card nicely, though there is some margin top/bottom. Not sure if my card is short or if the frame is long or they are both within the tolerances of typical T206s. Either way, it seems to hold the card securely and works much better than a toploader alone.
I really like the fact that it protects the card while not sealing it in a plastic tomb. I'm not a fanatic of razor sharp corners and perfect surfaces, so I feel like I can judge those aspects of a card as good or better than a TPA. And using the frame, I can still touch the raw card if I desire.
