As you will know from the low price, these are "educational quality" double-convex lenses, with unfinished, slightly rough edges and some tiny nicks around the rim, but the optical surfaces look reasonable viewed on-axis. No major digs or scratches. Focal length is just about 50 mm, and they are 5.32 to 5.65 mm thick at the center, 1.5 to 1.8 mm thick at the edge, and 29.6 to 30.0 mm in diameter. I received the expected qty (6) that I ordered. They came with each lens wrapped separately in bubble wrap. They are just the basic low-quality but functional lenses I expected. I got them to help collimate the light from a small flashlight in a quick desktop experiment, and they are suitable for that purpose.
