These really are 5mm... the pictures make them seem much bigger
I bought these based on the pictures... I didn't need anything exact, just something to focus some light. I saw that the measurement was 5mm, but the picture clearly shows something larger, so I took a chance. These really do have a diameter of 5mm. That's fine for my purposes... I just needed something for my science students to play with when we have our optics unit. We have big convex lenses in the science prep room already... the kids will get a kick out of seeing these, though. But just know, these are tiny. Other than that, they are fine. No scratches, nothing broken.

Worked for me
I got these to go into a spectrometer that I'm building for fun. These lens let me focus light going into and coming out of a diffraction grating and pass the light into a photosensor. The measurements of the lens they provide are accurate, and I was able to use them to 3d print a holder for the lens. Overall I'm happy with the product.
