I see you bought 4. It's why I bought 3 myself trying to get a match. Still my lefts are odd. I actually went to buy a 4th but the stems were gone by the time I did. It's ok though. Im happy with them. I even helped 2 forum members out getting frames to their respective countries. I refused to look at theirs when they came in for fear they were better than mine . Lol.I sealed my arms around to best match, two of the pair, arms and orbitals are almost the same.
