3D Spectacles Glasses Clip-on Glasses for RealD & IMAX 3000B

The 3D glasses overall came in a very nice case and box, and shipping was not a problem at all. However, the biggest crime is that these glasses were lazily put together. When I received them, one of the lenses was flipped and screwed in the wrong way, so because of that I cannot use those ones until I find a way to unscrew the lens. Also, the box did not come with a set of instructions that differentiates which is for IMAX 3D and which is for Real D 3D. So not only was it not put together properly, but also how do I know which is which?

I’m sure these glasses are high quality, because they look like they were made with decent parts and you can tell that they are meant for 3D due to their characteristics. However, I just can’t help but feel like whoever was responsible for this specific pair of glasses being made just simply had no idea how to do their job, or just did not care at the moment, and that’s very disappointing to me. I truly hope that is not the case.
