Accurate Specs, Good Quality Perfect for Small Optical Mods
These lenses are exactly as described. The sizing is precise down to the millimeter, and what you see in the listing is exactly what you get. The quality is surprisingly good for such small optics. I picked them up for a little side project involving a tiny indicator light on my Meta Ray-Bans, and they performed exactly the way I needed them to. They focus light well, theyโre consistent across all five pieces, and theyโre easy to work with if you do micro-mods or hobby optics. Overall, great little lenses simple, accurate, and because of that they fit perfectly on arrival.

Plant vase filler
Perfect for my plants I bought 2 bags but I didn't fill up the jars because I also added rocks

Seller is awesome
Very nice quality lenses. I needed them for a Halloween project so Iโve got plenty of time now. To the seller, thank you for your help in getting these to me. Perfect communications and a pleasure to work with. I would absolutely recommend the seller and their products

Clear and uniform
I bought these to use for a lense in a 3D printed toy "raygun" made to go with a Halloween costume. The bright blue LED I used for this shined brightly through the lens. They worked great for my purpose.

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.

4mm has a LOT of defects and cracks (all 5!) Don't look closely and you might be ok.
Depends on what you want to use these for- hobby models and toys? Probably ok. Actual optics- probably not. This isn't the best photo- its a view of the lens sitting on a fluorescent bulb using a phone- but even here you can see all the cracks and inclusions. Keep your expectations low maybe you'll be content- I mean a 5 pack, prime shipping for like $7? Hard to complain all THAT much but I'll do my best!
